| 摘 要： | 用Ｃｕ２＋离子将壳聚糖螯合基团保护后再用戊二醛交联，制得螯合基团得到保护的戊二醛－壳聚糖树脂，利用该树脂对Ｐｔ的酸性溶液在不同酸度、溶液浓度及树脂用量条件下进行了静态吸附实验。结果表明：在ｐＨ＝１、树脂用量为２０ｍｇ和铂（Ⅱ）离子浓度１００ｍｇ／ｌ时，该树脂对Ｐｔ（Ⅱ）吸附容量达为５４．７ｍｇＰｔ／ｇ干树脂，此外，对酸度影响吸附性能的机理作了讨论。

| Abstract: | In this paper pentanedialchitosan resin was sythesized by the method of protection of -NH 2 in Cu 2+ .The condition experiments of adsorption of Pt chloride in acid solution by this sythetic resin have been studied. The experimental results obtained show that when pH is about 1,Pt(Ⅱ)ion concertration is 100μg/ml and 20mg resin is usein is used ,the resin adsorption quantity is 54.7mg Pt/g(resin),and the adsorption rate is controled by inner diffusion. |
