Abstract

Wastewater of textile industry having impurities and heavy metal ions cause problems in human society that can endanger the human health through food chain. Adsorption of heavy metal ions before draining makes wastewater safe for aquatic life and human health. Now a day’s adsorption of heavy metal through polymeric nano adsorbents is the emerging technology which is more efficient than conventional adsorbents like activated carbon. The pH 9.0 gave maximum 96% sorption of Co at 1.0 g/L adsorbent dosage, due to increased electrostatic force of attraction produced by the negative charge at the surface of sorbent which is favorable for adsorbing cationic species. In the beginning of 15 minute retention time, metal ions adsorption was rapid due to availability of more number of adsorptive sites but further increase of retention time decreased the sorption capacity due to partial desorption that may occur due to the charge density and diameter of hydrated ions. Similarly in case of Cu, the maximum sorption was 95% at 7.0 pH using 1.0 g/L adsorbent dosage.
