Heavy metal pollution of waste water is a common environmental hazard, since the toxic metal ions dissolved can ultimately reach the top of the food chain and thus become a risk factor for human health. Chromium is present in waste water as trivalent and hexavalent. Trivalent chromium is relatively less toxic and less mobile while hexavalent chromium is toxic, carcinogenic, and mutagenic to animals as well as humans. Therefore, the removal of Cr (VI) from industrial waste water has been a research topic of great interest. In the present study carried out the comparative study of removal of the chromium (VI) from waste water by adsorption method. The search for new technologies involving the removal of toxic metals from wastewaters has directed attention to adsorption, based on metal binding capacities of various materials.

Keywords: Adsorption, biomass, concentration, efficiency, heavy metal
