研究了合成可交联硫化壳聚糖胺的方法．指出了用其作为吸附剂，对贵金属如Ｐｔ、Ａｕ等具有极高的吸附率和较好的吸附容量，对Ｐｔ的吸附率在９８％以上，对Ａｕ分别为８８％和０．７３ｍｍｏｌ／ｇ．用稀王水进行解析试验．其解析率对Ａｕ达９２％，但吸附剂不能再生．对Ｐｔ则不能解析．
The synthesis of crosslinkable sulfurized chitosan amine was studied. The results show that the adsorption rate of Pt is more than 98% for Au, 88% and 0.73 mmol / g for Au, respectively . Analyze the test with dilute aqua regia. The resolution of 92% of the Au, but the adsorbent can not be regenerated. Pt can not be resolved.
