摘要
以壳聚糖微球为原料,硝化棉-醋酸纤维素微孔滤膜为支撑体,制得强度较高的复合有序壳聚糖膜.研究了该膜与普通壳聚糖交联膜对Cu2+,Na+2种金属离子的渗透行为.发现Na+在复合有序壳聚糖膜中的透过率明显大于Cu2+,即该膜可选择性地让Na+离子透过而截留大部分Cu2+离子.
The permeation of Na+ and Cu 2+ ions through an orderly chitosan membrane supported on a base material was studied.It was found that the permeation rate of Na+ was larger than that of Cu 2+.The result showed that the orderly chitosan membrane could selectively allow Na+ to pass through,while retain the most of Cu 2+ ion.
