壳聚糖对金属铅离子吸附作用的研究

Study of the Adsorption Effect of Lead lons on Chitosan

摘要: 对壳聚糖对Ｐｂ＾２＋吸附作用进行了探讨。实验结果表明该吸附过程符合一级反应动力学过程，且为扩散控制步骤。吸附平衡数据表明吸附符合Ｌａｎｇｍｕｉｒ吸附等温线方程。实验结果同时也表明壳聚糖与Ｐｂ＾２＋之间存在着配位作用。

Abstract: The adsorption effect of lead ions on chitosan was investigated.The study of the adsorption kinetics showed that the rate of adsorption effect of lead ions on chitosan can be interpreted in terms of first order rcaction equation and the rate-limiting step
