| 摘 要： | 本文采用滴加成球法制备球形壳聚糖树脂，对影响壳聚糖树脂粒径分布的多种因素进行了研究。研究了用戊二醛，环氧氯丙烷及乙二醇环氧丙基醚作交联剂时，不同交联剂对树脂吸附Ｎｉ＾２＋、Ｃｕ＾２＋、Ｚｎ＾２＋的吸附动力学曲线及吸附等温线的影响。研究了ｐＨ值，颗粒粒径、离子强度对吸附容量的影响。

| Abstract: | Preparation of chitosan beads with a nozzle was investigated. Glutaraldehyde, Epichlorohydrin and ethylene glycol diglucidyl ether was used to cross linking the resin to enhance rigidity of resin. The adsorption kinetics and equilibrium isotherm of Ni~2 , Cu~2 , Zn~2 were determined with the chitosan resin and the influences of pH, particle diameter, ion strength on adsorption of metal ions were also studied. |
