Water Purification

Water is critical to human existence. The lack of a clean water supply not only affects health, but contaminated water from animal and human waste and chemical pollution and runoff is especially harmful. Access to clean water is a bigger problem than hunger in underdeveloped, war-torn, or natural disaster areas. In the United States, drinking water standards have been revised and water treatment methods are being changed to meet stricter contaminant standards. As the planet's population and agriculture needs require greater volumes of potable water, the need for better purification methods have become particularly important. The use of nanomaterials may offer big improvements to existing water purification techniques and materials and may well bring about new ones. They could also supply water treatment and purification in remote areas where electricity is not available.

Applications in Different Fields

After the tragedy of Sept. 11, 2001, concern over biological and chemical warfare has led to the development of handheld units with bio- and chemical sensors for the detection of biological germs, chemical or nerve agents, mustard agents, and chemical precursors to protect subways, airports, the water supply, and the population 1.29 .

Introduction The Canvas of Nano

Yet his manufacturing practices are primitive. Everyone knows that a lot more needs to be done to get closer to nature. For example, no one has reached the efficiency of photosynthesis in storing energy. No one can facilitate energy transfer (or electron transfer) as efficiently as biomolecules. No factory does water purification and storage as efficiently as coconut trees or water melons. The brain of one person can, in principle, store and process more information than today's computer. It is unlikely for any movie camera to capture visuals more vividly than the human eye. The olfactory receptors of the dog are much more sensitive than the sensors we have developed, though single molecule detectors have been reported. Most early warning systems are primitive when compared to the sixth sense

Abbreviations and Symbols

Few studies, however, have investigated the oxidation potential of ZVI. The recently discovered ZVI oxidative process and the further modified process in the presence of ethylenetetraaminediacetic acid (EDTA) are described, and the potential future applications are discussed. The discovered reaction processes can be widely used to treat pesticides, herbicides, and industrial chemicals and purify contaminated water for domestic use. One of the most interesting, and potentially least costly, methods for their degradation involves the use of elemental iron (Fe(0)). While Fe(0) or ZVI has been used principally to degrade contaminants in subsurface environments by placing ZVI barriers across the groundwater flowpath, the possibility also exists of using particulate ZVI, which could be either pumped into a contaminated aquifer or dispersed through contaminated sediments.

The Construction Case

At the same time there is a sector of great economic activity, the construction industry, dealing with coarse components consumed in large amounts seeking necessary innovations. The construction industry is also a great integrator of solutions offered by other industrial sectors i.e. a building integrates water supply, heating, ventilation and communication systems, etc.

Richard E Smalley 19432D05

To many people, Richard Smalley was the foremost leader in nanotechnol-ogy. He has often been noted as the Father of Nanotechnology. Richard Smalley was a Rice University professor who won the Nobel Prize in chemistry in 1996. Richard Smalley is mostly known for his work with carbon nanotubes, (known as the Buckyballs). Smalley was hopeful that nanotechnology could solve the global energy problem, which would ultimately solve other worldwide problems such as hunger and water shortages. He believed the potential for nanotechnology to benefit humanity was virtually limitless, and he abided by the mantra Be a scientist save the world.

Use of ZVI H2O 2 and Complexants

The feasibility of Fenton's oxidation of methyl ierf-butyl ether (MTBE) using ZVI as the source of catalytic ferrous iron was assessed in a study by Bergendahl and Thies (2004). More than 99 of MTBE-contaminated water was removed at pHs 4 and 7 using a H2O2 MTBE molar ratio of 220 1. Similarly, Lucking et al. (1998) investigated the oxidation of 4-chlorophenol in aqueous solution by hydrogen peroxide in the presence of a variety of additional substrates including iron powder. H2O2 oxidation of 4-chlorophenol in the presence of iron powder proceeded much faster when iron powder was used instead of graphite or activated carbon, presumably via Fenton's oxidation of the 4-chlorophenol. Studies by Tang and Chen (1996) showed the degradation of azo dyes was faster using the H2O2 iron powder system than the Fenton's reagent system, e.g., H2O2 Fe(II). The difference was attributed to the continuous dissolution of Fe(II) from the iron powder and the dye adsorption on the powder.

Dimensions Of The Problem

Wars have been fought, and will continue to be fought, over access and control of clean water. Drinking water has two major classes of contamination biological contamination and chemical contamination. Bacterial contamination can be dealt with by a number of well-established technologies e.g., chlorination, ozone, ultraviolet (UV), etc. , but chemical contamination is a somewhat more challenging target. Organic contaminants, such as pesticides, agricultural chemicals, industrial solvents, and fuels, can be removed by treatment with UV ozone, activated carbon, or plasma technologies. Toxic heavy metals such as mercury, lead, and cadmium can be partially addressed by using traditional sorbent materials such as alumina, but these materials bind metal ions non-specifically and can be saturated with harmless, ubiquitous species such as calcium, magnesium, and zinc (which are actually nutrients, and do not need to be removed). Another weakness of these traditional sorbent...

Nanoscience And Its Role

Clearly, all these toxic metals form a significant threat to the water supplies of the world. How can nanoscience address this problem A chemically specific sorbent material capable of permanently sequestering these toxic metal ions from groundwater supplies is needed to purify contaminated drinking water. Because we consume vast quantities of drinking water every day, the kinetics of heavy metal sorption need to be fast, allowing for high throughput in the process stream. A high binding capacity for the target heavy metal is clearly of value. In addition, as acceptable drinking water contamination limits becomes

Environmental degradation or sustainability

Human and livestock pressure on the land has created worsening desertification in China, land of 1.3 billion people, and soil erosion is reducing arable land and affecting water supplies in many other areas of the world. About one third of the world's population lives in nations experiencing water shortages, and the proportion is rising. The recent intensive and comprehensive Millennium Ecosystem Assessment concludes that about 60 per cent of the planet's 'ecosystem services' are being degraded or used unsustainably. It catalogues a destabilizing loss of fish-stocks, forests, mangroves, coral reefs, natural water cycles and so on (Graham-Rowe and Holmes, 2005). The general On the negative side, nanotechnology will cumulatively be appropriated by the existing forces of consumer production, advertising and marketing. Unless there is coordinated scrutiny and regulation, nanotechnologies may be introduced with the old mistake of ignoring or neglecting any potential external costs they may...

Cleaner water for less money

One direction being looked at for cleaning water involves production of nanoparticles that use less expensive materials than palladium, the current industry standard. One idea Inject iron nanoparticles into a contaminated body of water, as illustrated in Figure 9-4. The particles would then spread throughout the water, cleaning it in the process. This would be much faster and cheaper than conventional methods that involve pumping the contaminated water out of the ground before treating it.

Water Pollution And Nanotechnology

By 2015, approximately 3 billion people will live in countries where it will be difficult to get enough water for basic needs. More than 1 billion people will lack access to clean drinking water, while others will die from contaminated water. The Environmental Protection Agency (EPA) estimates that at least 500,000 cases of illnesses annually can be attributed to contaminated drinking water in the United States.

Cleaning Up Organic Pollutants Using Nanotechnology

TCE can be absorbed through the lungs, mucous membranes, gastrointestinal tract, and the skin. Exposure to TCE happens mostly from breathing contaminated air and drinking contaminated water. Short-term exposure to high levels of this chemical can result in toxic effects on a number of organs and systems, including the liver, kidney, blood, skin, immune system, reproductive system, nervous system, and cardiovascular system. In humans, acute inhalation exposure to TCE causes central nervous system symptoms such as headache, dizziness, nausea, and unconsciousness. TCE has been linked to liver damage, impaired pregnancies, and cancer.

What is the most common or traditional method that is used for groundwater remediation

The constant daily pumping operation is costly. Ex situ process can also be tied up in legal and regulatory issues because once the contaminated water is pumped up to the surface you cannot just dump it back on the ground again because it is hazardous waste, so you need to go through regulatory and legal requirements to remove it. The iron wall or permeable reactive barriers (PRBs) has two main characteristics it is in situ and it is passive. In situ means that you apply iron particles by placing them into the ground and treat the contamination there. You do not have to pump the contaminated water up to the surface. The other advantage is that this method is passive. Pump and treat is active because you have to constantly keep the pumps working. Ideally passive technologies mean that once the treatment is in place you can cover it up, plant grass, and then you can leave the area there is nothing else to do.

Traditional Applications

Discoloration of sugar, air purification, removal of odor or toxic gases, water purification, gas separation, solvent recovery, etc. have been the traditional application areas of porous carbons. Most of these applications are based on the superior adsorption properties. Of course, the pore sizes of the activated carbons are different among the various applications by controlled production of activated carbons. Because the readers may find a suitable book for activated carbons that describes these historical usages of the activated carbons 132 , we will review contemporary applications of porous carbons.

Conclusion and Nanoperspective

Developing near-term commercially viable products is of vital importance for the development of the nanofield. Near-term opportunities of nanomaterials lie in functional nano-materials such as tougher and harder cutting tools, the superplasticity of ceramics during processing, high performance parts for the aerospace and the building industry, energy and filter technologies (novel solar cells and water purification), the automobile industry, optical and catalytic applications, and sensors. On a longer term, and dependent on the developments in the electronic industry, (opto)electronic applications of nanomaterials such as photonics may find a big market. Interdisciplinary cooperation in research and development is important for the realization of scientific breakthroughs and for new products such as hybrid coatings or nanoelectronic devices. Currently, the preparation technology of nanomaterials plays an important

Artificial Evolution How Green is Green Nanotechnology

Chiefly related to the absorption of nanoparticles by the human body and their distribution as well as the risk of accumulation in organs. It is also unknown, as to how the human (and animal) metabolism will react to the intake of nano-engineered food and nanoparticles, which once introduced in the ecosystem, will enter the food chain. This necessitates research into the possible negative impacts of bio-nanotech, and transparency in the results in view of the credibility and plausibility of green nanotechnology. However, recent results obtained suggest that the benefits far outweigh the risks (e.g., applied nanotech techniques for water purification systems).

The Role of Federal Research Laboratories

As an example of federal laboratory activities, consider technology transfer efforts at one of the leading nanotechnology laboratories at NASA Ames Research Center. The research focus at NASA Ames is on nanomaterials such as carbon nanotubes, inorganic nanowires, conducting organic molecules, and protein nanotubes. The applications focus for these nanomaterials is diverse nanoelectronics, computing, data storage, nanoscale lasers, chemical sensors and biosensors, ultraviolet and infrared detectors, and advanced life-support systems that address waste remediation, air purification, and water purification as well as instrumentation for planetary exploration and astronaut health monitoring devices.

Advanced Oxidation Processes

Liquid-solid and gas-solid are two representative heterogeneous photocatalysis reactions for pollutant remediation in water and air, respectively. Vast amounts of photocatalysis research have dealt with the liquid phase 2, 5, 7 , with relatively less work carried out on gas-phase systems 7, 140145 . For gas-phase reactions, O2, which is adsorbed with H2O molecules on the catalyst surface, can largely improve the oxidation reaction. Although O2 molecules are not only electron scavengers but also the main radicals with oxygen-derived formations (O- and HO2, etc.) that oxidize organic molecules, the existence of O2 alone is found to be inefficient for oxidation. H2O is necessary to improve photooxi-dation reactions in gas-phase systems. The role of H2O in the gas-phase reaction is complicated and still not very clear. Fourier transform infrared studies revealed that the photodegradation rate of 4-CP was dramatically enhanced in the presence of water, but the action of water was not known...

Role of Fullerenelike Structures in the Reactivity of Shungite Carbon as Used in New Materials with Advanced Properties

The work highlights a source of unusual high reactivity of shungite carbon (ShC) as a catalyst in modeling coal-treatment reactions, a filler for polymeric matrices, an adsorbent and filter for a water-purification process, and a reagent in melting of siliceous iron and in the production of silica carbide. The structural pattern of ShC was shown to be connected with fullerene-like structures which could be released under different conditions, providing its activation and determining reactivity of ShC containing materials. Fullerenes are likely to be present in ShC as chemical derivatives and strong molecular complexes. It was proposed to liberate fullerenes and fullerene-like structures while processing the ShC. Artificial fullerenes display an effect similar to that of ShC in modeling the reaction of coal treatment. Fullerene-like structures, both synthetic and those liberated from natural carbon, are capable of acting as a hydro-genated catalyst at low temperatures. Owing to the...

Separation by Solution Diffusion Process

Asymmetric Membrane

The mixture flows through modules, where it passes along the membranes. The component to be removed is vaporized through the membranes and collected at very low pressure in a vacuum vessel. It is then condensed and purged out. A vacuum pump extracts the noncondensables and maintains the required vacuum. This vaporization cools down the processed mixture, which must be reheated to maintain the highest flux through membranes. Main applications are wine and beer dealcoholization, removal of organic solvents from aqueous streams, aroma recovery and concentration, and waste water purification.

Pesticides Treatment and Management Practices

The feasibility of bioremediation depends on the specific contaminant and its suitability as a substrate for microbial degradation. The planned future use of the site is also an important consideration (Arthur and Coats, 1998). Detailed site characterization and preliminary feasibility studies are required for the design and optimization of any biostimulation approach. Remediation also depends on the site-specific nature of each contaminated matrix (Zablotowicz et al., 1998). A bioactive soil barrier technique, known as the Filter technique, which combines the use of contaminated water with filtration through the soil to a subsurface drainage, has been found to reduce pesticide loads by up to 99 (Jayawardane et al., 2001). However, field studies have shown that the concentration of pesticides in the discharge, particularly mobile ones such as molinate, are often found above accepted environmental limits (Biswas et al., 2000).

Harnessing Nanotechnology for Sustainable Development

Safe Drinking Water Among the numerous possible applications of nanotechnology, the most widespread impact as far as the developing world is concerned may be in the area of water purification. Access to safe drinking water is one of the major concerns in the developing world since almost half of the world population has no access to safe drinking water and basic sanitation. Water purification systems, equipped with nanomaterials and using new kinds of membrane technologies with variable pore sizes as filters, could provide people in any area with safe drinking water. These are easy in application and maintenance, and are already available in the market the forward-osmosis membrane technology of Hydration Technologies (Ref. 19) is one technique utilising nanotechnology. Thus a combination of nanotechnologies will be useful in providing safe drinking water through cost-effective measures, which will be less dependent on energy resources. Although the product is currently marketed only...

Analyzing the Data

Finally, there is an information deficit on the degree humans will be exposed to different nanomaterials. The most hazardous chemicals may not have toxic effects if the exposure is minimal, and relatively inert chemicals may be highly toxic at certain levels.56 Chemicals can enter the human body through oral ingestion, inhalation, or dermal absorption. Direct exposure involves nanomaterials entering humans during manufacturing or life cycles of the products in which they are used. An example of direct exposure would be workers at manufacturing plants inhaling carbon nanotubes. It is difficult to estimate direct exposure levels. Even when nanomaterials enter the environment, they may not form respirable particles. For example, two recent exposure assessment studies found that individuals working with nanotubes are exposed to very low levels of nanotube dust.57 Indirect exposure to nano-materials would take place if nanomaterials got into the water supply or food chain. There are also...

Ceramic Membranes

The integration of nanocatalysts into water treatment provides improved options. Nanocatalysts are substances materials with catalytic properties that have at least one nanoscale dimension. Since their greater surface area provides more contact with reactants, they are more efficient than larger materials. These materials could be used in specific applications where contaminated groundwater is already being treated. Nanocatalysts could be activated by common water purification methods, used as treatment additives, and recovered by nanomembranes. Figure 7-2 shows a portion of a nanostructured membrane created from particle templating.


Although nanofiltration membranes are important in water purification, nanoparti-cles either in solution or attached to membranes can help ensure that pollutants chemically degrade and don't just travel somewhere else. Nanocatalysts are currently being studied for their environmental applications. Catalytic treatments can lower polluted water treatment costs by making it possible for purification methods to be specifically designed to treat chemicals at a particular site.


Ultrafiltration membranes that reject particles and macro-molecules of 2-100 nm in size are used for water purification, blood dialysis and food processing. They are generally made by phase inversion of polymer solutions or through the phase separation of polymer blends1,2. Reverse osmosis membranes are used for the production of drinking water from seawater and to concentrate milk, sugars, fruit juice and other products in the food industry. They are usually prepared by interfacial polymerization and often used in combination with ultrafiltration membranes2'4. Nanofiltration membranes have similarities with both ultrafiltration membranes and reverse osmosis membranes in that they can block multivalent ions and small organics, which is useful for water softening, the removal of micropollutants, and the recovery of dyes from waste water. Nanofiltration membranes are usually prepared either by interfacial polymerization or phase inversion12.

Greenhouse effect

The greenhouse effect covers a wide range of effects that result from the warming of the earth's atmosphere. Among these are not only the rising mean sea level, but also the increase in extreme climatic weather conditions such as hurricanes, storm floods, catastrophic drought, etc. Changes in the composition and the range of flora and fauna are also already being looked at.


The simplest method to introduce ligands is by blending ligand molecules into the polymer solution and then electrospinning the polymer solution. For example, an attempt 35 was made to incorporate chemically modified p-CD onto the surface of the nanofiber to target potential applications in organic waste treatment for water purification. Phenylcarbomylated or azido phenylcarbomy-lated p-CD was successfully blended with polymethyl methacrylate (PMMA) and electrospun into nanofibrous membrane, respectively. The presence of the p-CD derivatives on the surface of the nanofibers was confirmed by attenuated total reflectance fourier transform infrared spectrometry (ATR-FTIR) and X-ray photo-electron spectroscopy (XPS). To determine the functionalized membranes' ability to capture small organic molecules, a solution containing phenolphthalein (PHP), a small organic molecule, was used. Results obtained showed that the functional-ized nanofibrous membranes were able to capture the PHP...
