摘要: 淀粉改性官能团化作为金属离子的吸附剂用于废水处理已有报道[1~3],但吸附效果不理想,应用范围受限制。本文将玉米淀粉接枝甲基丙烯酸缩水甘油酯共聚物(Cs-g-PGMA)与甘氨酸反应,得到Cs-g-PGMA-Gly作为吸附剂,可以去除水中的Cd2+、Cr3+等有害元素,而且在适当的pH条件下还可富集分离Au3+、Pd2+

Abstract: The graft copolymer of glycidyl methacrylate(GMA) onto corn starch has been reactedwith glycine. The products, Cs-g-PGMA-Gly, are able to adsorb metal ions, such as Au3+,Pd2+, Cr3+, and Cd2+ in high percentage.

Key words: corn starch, glycidyl methacrylate, glycine, graft copolymer, adsorbability, Au3+, Pd2+, Cr3+, Cd2+
