| 摘 要： | 本文研究羧甲基壳聚糖对Pb^2 的吸附作用，探讨反应时间，离子强度，溶液的PH值、羧甲基取代度，温度等因素对吸附性能的影响，结果表明羧基是吸附Pb^2 的主要活性基团，羧甲基壳聚糖对Pb^2 的饱和吸附量为3．1083mmol/g，吸附Pb^2 的能力比壳聚糖，水溶性低聚壳聚糖强。

| Abstract: | The effects of various factors: reaction time, ionic strength, pH value, substitution degree of carboxymethyl group and temperature on the adsorption behavior for Pb~(2+) on carboxymethyl chitosan were investigated. The results showed that carboxymethyl chitosan had higher adsorption capacities than chitosan and water-soluble low-molecular weight chitosan, the former's adsorption capacity for Pb~(2+) was 3.1083mmol/g. |
