Removal of Hexavalent Chromium from Wastewater by Adsorption: A Review

Amount of waste water containing heavy metals is increasing in the environment due to industrialization. Heavy metals treatment of waste water should be done due to increase in pollution and scarcity of water. Hexavalent Chromium is one of the heavy metal emitted from textile dye, tannery, nuclear power plants, and battery making steel and electroplating industries which cause chronic disorders in human. It is one of the most common metal present in the effluents. So it is necessary to remove heavy metals from waste water as it is very toxic. The study was carried out to increase the percentage removal of hexavalent chromium, characteristics, efficiency and economy of waste water by low cost adsorbent.
