PHYSICOCHEMICAL PROPERTIES OF COPPER (II) ION ADSORPTION IN A POLYMER COMPOSITE OBTAINED BASED ON CHITOSAN
Based on chitosan obtained from local raw materials (Calliptamus italicus L.), a polymer composite sorbent with a static exchange capacity (SEC) of 2.43 mg-eq/g was synthesized. UV-Vis and IR spectroscopic, as well as X-ray fluorescence physicochemical analysis methods, were used to study the sorption of Cu(II) ions on the synthesized sorbent. The dependence of sorption on solution pH, concentration, and time was investigated
