SYNTHESIS AND ADSORPTION CHARACTERIZATION OF CARBOXYMETHYL CROSSLINKED CHITOAN RESIN
天然高分子吸附剂研究——羧甲基交联壳聚糖树脂的合成及吸附特性

Carboxymethyl crosslinded chitosan resin was synthesized through the reaction of chitosan crosslinked by ethylene glycol bisglycidyl ether with chloroacetic acid. Its static adsorption properties for Cu2+ , Ni2+ , Co2+ were studied. The results showed that the resin has good adsorption properties for metal ions studied and the capacities of absorption were 2.25, 1.98 and 1.81 mmol·g-1 , respectively.
