Abstract
Urbanization and Industrialization have led to release of higher heavy metals amounts into the atmosphere especially aqueous regions. Heavy metals contaminations of potable water have become a serious challenge especially with toxic elements like mercury, lead, zinc, boron and cadmium. Lot of biological constituents has attracted many scientists and researchers due to qualities of cheap and effectiveness for removing heavy metals from waste water. The nanostructured adsorbents exhibit much higher effectiveness and faster rates of adsorption in treatment of water as compared to conservative materials principally because of the remarkably higher surface areas. In the current review, it has been described that the nanomaterials can be used successfully as cost-effective, ecologically friendly, and efficient adsorbents for the elimination of different toxic substances from wastewater.
