0. The removal was fast during the initial contact time and the adsorption data obtained at various contact time were fit well to the pseudo-second order kinetic model. The maximum sorption capacity for Cu2+ was found to be 17.30 mg/g whereas Pb2+ was found to be 107.52 mg/g. The presence of MgCl2, NaCl and KCl did not cause significant influence on the removal of Cu2+ and Pb2+ using ABn-AG. Binary adsorption study suggested that Cu2+ and Pb2+ were removed through different binding sites present in ABn-AG. Reusability test showed that removal of Cu2+ and Pb
