摘要
在稀醋酸溶液中 ,微波辐射下壳聚糖与Zn2 + 反应形成壳聚糖Zn2 + 配合物。该配合物与乙醇双环氧丙基醚在微波辐射下进行交联反应 ,用稀酸除去Zn2 + ,合成了具有Zn2 + 孔穴的交联壳聚糖树脂。试验了该树脂对一些金属离子的吸附性能 ,并对影响树脂吸附性能的因素进行了研究。
Chitosan reacts with Zn 2+ into Zn 2+ -chitosan complexes in dilute accetic acid solution under microwave irradiation.The complexes cross-linkswith EGBE as cross-linking agent under microwave irradiation,Zn 2+ being removed with dilute acid,a new cross-linked chitosan resin with Zn(Ⅱ) cavtitycan be synthesized. The adsorption properties of the resin for Zn 2+ ,Cu 2+ ,Ni 2+ and Co 2+ are examined and influence factors on adsorption capacity of the resin are investigated.
