中文摘要：

以丙烯酸改性壳聚糖为研究对象,采用离子印迹法制备了镉模板交联壳聚糖吸附剂（PACS）,改变壳聚糖与丙烯酸的质量比探究其吸附效果,对产物进行扫描电子显微镜和红外光谱表征,并研究了该吸附剂对Cd2＋的吸附效果。实验结果表明,当丙烯酸与壳聚糖的质量比为1.5∶1时制得的吸附剂最好,溶液吸附最佳pH为5,其最大吸附量可达132.1 mg/g。该吸附剂能再生,可用于含Cd2＋废水的去除或富集。

英文摘要：

Glutaraldehyde- crosslinked acrylic acid- modified chitosan adsorbent（ PACS） was prepared using Cd （Ⅱ） as a template ion. Mass ratio of acrylic acid to chitosan was tested to find the most suitable adsorption effects.The adsorbent was characterized by SEM and FT-IR and its adsorption for Cd2＋was evaluated. When the mass ratio of acrylic acid to chitosan was 1. 5 ∶1,the obtained adsorbent for Cd2＋had the highest uptake of 132. 1 mg / g at p H 5.The adsorbent can be recycled. Therefore,the PACS is an effective sorbent for the removal or collection of Cd2＋from effluents.
