Adsorption is a unit process to control pollution in water and wastewater technology. Carbon adsorption is widely used for the removal of refractory organic compounds from wastewater. GAC (Granular Activated Carbon) is used as a adsorbent for heavy metals like Nickel, Copper, Chromium etc. by modifying it in Modified Granular Activated Carbon. In this work, adsorption of Copper on activated carbons is carried out from oxidation treatments with HNO 3 to GAC. The oxidation treatments determined an increase adsorption capacity on the surface by functional groups. By performing Batch experiments the study of Copper ions from synthetic solution on Modified GAC & their recovery was studied at constant temp 28°C±. By varying concentration of Cu 2 + solution. The parameters for the Langmuir and Freundlich parameters has been also studied by showing maximum adsorption capacity of copper by MGAC. The oxidation treatments determined an increase adsorption capacity on the surface by functional groups.
