Turning to Nanotechnology for Water PollutionControl: 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 usingthis cutting edge technology not only to develop incredible new products, but also towork towards cleaning water. Recently, heavy metal contamination has develop to be theessential serious ecological issues. The treatment of heavy metals is of special concern inthe environment. As of late, different techniques for removal of heavy metal ions fromwastewater have been widely considered. Adsorption is a standout amongst the mostsimple and productive process for treating industrial effluents, and a helpful mechanism tosafeguard the ecosystem. The uses of novel nano-adsorbent for the treatment of waste waterare confirmed by the continuous increment in research articles publication on adsorptionof heavy metal ions using organic-inorganic nanocomposites. The present article highlightsthe late advancements in the preparation of nano adsorbents incorporating polymer-silicahybrid materials by sol-gel technique. The primary goal of the present review is to depictthe versatile nature of polymer-silica hybrid materials and their ability to absorb varietyof heavy metal ions which are present in the wastewater. An endeavor is likewise beingmade to incorporate adequate data like the strategy for synthesis of polymer-silica hybridmaterials, structure, their adsorption capacity, variables affecting the adsorption and theplausible mechanism involve in adsorption of heavy metal ions from contaminated water.
