• 摘要：以壳聚糖为原料，经乙二醇双缩水甘油醚交联后，与氯乙酸反应，合成了羧甲基交联壳聚糖树脂，并研究了其对Cu²⁺, Ni²⁺, Co²⁺的静态吸附性能，结果表明，该树脂对上述3种金属离子均具有良好的吸附性能，其吸附容量分别达2.25, 1.98和1.81mmolg^-1.

• Abstract：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.

• Key words：carboxymethyl chitosan  adsorption resin  metal.
