ABSTRACT
The present study focuses on the preparation of chitosan and chitosan-derived resin and their application in the removal of Ag(I) from aqueous systems. Chitosan was modified with epichlorohydrin, followed by 1-methylimidazole through microwave-assisted modification. The modified chitosan was capable of adsorbing as much as 77 mg of Ag(I) per gram. The sorption kinetics were best described by the pseudo-first-order model. Additionally, the bioresin maintained its Ag(I) sorption capacity after five repeated sorption and desorption cycles.
