Turning to Nanotechnology for Water Pollution Control: Applications of Nanocomposites

A new wave of science innovation is based on something much smaller than ever before. Nanotechnology is the hottest buzz in laboratories around the world. Scientists are using this cutting edge technology not only to develop incredible new products, but also to work towards cleaning water. Recently, heavy metal contamination has develop to be the essential serious ecological issues. The treatment of heavy metals is of special concern in the environment. As of late, different techniques for removal of heavy metal ions from wastewater have been widely considered. Adsorption is a standout amongst the most simple and productive process for treating industrial effluents, and a helpful mechanism to safeguard the ecosystem. The uses of novel nano-adsorbent for the treatment of waste water are confirmed by the continuous increment in research articles publication on adsorption of heavy metal ions using organic-inorganic nanocomposites. The present article highlights the late advancements in the preparation of nano adsorbents incorporating polymer-silica hybrid materials by sol-gel technique. The primary goal of the present review is to depict the versatile nature of polymer-silica hybrid materials and their ability to absorb variety of heavy metal ions which are present in the wastewater. An endeavor is likewise being made to incorporate adequate data like the strategy for synthesis of polymer-silica hybrid materials, structure, their adsorption capacity, variables affecting the adsorption and the plausible mechanism involve in adsorption of heavy metal ions from contaminated water.
