Pollution has become a major issue due to its impact on environment. One of the major cause for pollution is the rapid industrialization. The effluent discharged from the industry have adverse effect on environment. Due to development there is also increase in various types of industries like paint, tanning, electroplating etc. These industries contains Cr (VI) in its effluent that contaminate water as well as soil. As hexavalent chromium is in dissolved form it is more toxic to living cells. So there is a need to detoxify it from effluent before allowing it to enter in soil and water resources. In this paper household kitchen residues are used for the detoxification of hexavalent chromium from the metal containing solution. The household waste material like Tea powder, Egg shells, Coconut coir, Orange peel and Sugarcane bagasses is used to detoxify Cr (VI) from metal solution. The residual chromium was estimated by an assay performed using 1, 5-Diphenyl Carbazide (DPC) method.
