| 摘 要： | 壳聚糖（Chitosan,CTS）是自然界中储量仅次于纤维素的最丰富的天然高分子材料,其大分子链上含有较多的羟基、氨基等活性基团,已广泛用作各种载体材料.本文研究了壳聚糖对Ag＋的吸附性能,考察了不同条件下壳聚糖对Ag＋的吸附关系.pH值的提高和作用时间的延长均使吸附率增加,而较低温度下更有利于Ag＋的吸附,初始Ag＋浓度的高低对吸附量影响较大.

| Abstract: | Chitosan(CTS) is the most abundant natural macromolecule materials in nature expect cellulose.It is applied for vary carrier materials due to containing more hydroxyl and amino groups in the molecular chain.This paper studied the adsorption properties of chitosan for Ag~ ,and adsorption relationship between chitosan and Ag~ under different conditions.With rising of pH and extension of adsorbent time,the adsorption rate increases gradually.Lower temperature makes for adsorption of Ag~ .And there is no linear relationship of the adsorption rates of CTS for Ag~ at the different initial concentrations of Ag~ . |

| Keywords: | chitosan adsorption Ag~ adsorption rate |
