Abstract
A new hydrogel based on a modified chitosan CS-B was synthesized and evaluated for its metal ion
removal from aqueous systems. The CS-B hydrogel was prepared through modification of chitosan with 4-
((1, 3-dioxoisoindolin-2-ylimino) methyl) benzaldehyde as a heterocyclic component. The new hydrogel
was analyzed by diverse techniques such as FTIR, XRD, TGA, SEM, and swelling tests. The adsorption
capacity of CS-B for metal ions Co2+, Hg2+, Cu2+, Zn2+, and Pb2+ from aqueous systems at different pH
values showed various levels of efficiency. The metal ion uptake data over a range of pH values for Co2+
and Hg2+ showed the highest adsorption capacity while Cu2+, Zn2+, and Pb2+ showed moderate adsorption
capacity. Selective metal ion efficiency was highest for Co2+ and lowest for Hg2+ in their binary mixture.
