Sorption studies on the removal of copper onto biopolymer derivative: chitosan-g-maliec anhydride-g-ethylene dimethacrylate

Abstract

The current work suggests employing an unique Chitosan-g-Maleic anhydride-g-ethylene dimethacrylate copolymer to remove the harmful heavy element copper. By adjusting variables like the concentration of the monomer, the concentration of the initiator, and the temperature during the chain polymerization reaction, the graft copolymer was developed. The copolymer obtained at the optimum condition was picked out to study its adsorption property towards Cu²⁺ ions. The adsorption factors, such as the amount of adsorbent, contact time, pH, and initial concentration of the metal solution, which affect the adsorption process, were looked at using the batch adsorption mode. Freundlich and Langmuir isotherm models were applied to analyse the equilibrium adsorption.
