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．
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 Cu 2+ ,Ni 2+ ,Co 2+ 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.
