Abstract

Textile industries are known to be huge platform for providing employment without any skill perfection but at the same time they also hold the tag of prime offender in polluting the environment. They are immensely responsible for discharging the heavy metals to the aquatic bodies. Heavy metals such as Copper (Cu), Lead (Pb), Cadmium (Cd), Chromium (Cr), Arsenic (As), Zinc(Zn), Iron (Fe), Mercury (Hg), and Sulphur (S) are widely used in textile industries. These heavy metals are the great threat for the environment and ecology. This proposed work is done to evaluate the efficiency of wheat husk in removing of heavy metals from textile Effluent. Wheat husk was subjected to different steps of physical and chemical treatment and was converted into activated carbon. Textile effluent was collected from Tirupur area in Tamilnadu which is very famous for the cotton industries. Batch studies were done by taking 10 g of wheat husk with 200 mL of the textile effluent to evaluate change in the Heavy metal concentration from initial state to final state in the collected sample from textile effluent. The pH of the sample was varied from 4.5 to 7.5 and the adsorption capacity of wheat husk was analyzed for Arsenic, Mercury Chromium and Lead. Initial characterization of Heavy metals is done by using PERKIN ELMER OPTIMA 5300 DV ICPOES. The results show that this low cost and eco-friendly adsorbents can effectively used for the removal of heavy metals.
