| 摘 要： | 本文提出了利用脱乙酰甲壳质富集微量银的一种新方法。详细研究了溶液酸度、吸附时间及脱乙酰基程度对Ａｇ＋吸附量的影响，吸附量可达５９．４ｍｇ／ｇ．按一定方法洗脱被吸附的Ａｇ＋后脱乙酰甲壳质可再生。将甲壳质装柱处理实验室含Ａｇ＋废液，回收率可达９６．５％．经再生的甲壳质反复使用多次，对Ａｇ＋的吸附效果基本不变。

| Abstract: | A new method of enriching trace silver with chitosan is reported.The optimal conditions are investigated.And the sorption capacity of chitosan for Ag+ is 65.0mg/g.Eluated the adsorbed Ag+ from chitosan,the chitosan can be recycled After the silver wastewater passing through a column filled with chitosan,the rate of Ag+ recovery reaches 96.5%.The sorption capacity is stable basically when the renewed chitosan is used many times. |
