摘　　要：合成了4种偶氮化合物与淀粉的接枝共聚物的不溶性树脂,首次用以吸附二价金属离子,研究了其静态吸附量以及各种相关因素对吸附的影响。Four types of starch derivatives containing azo groups were used in removal of some metal ions from their solutions, and the different factors affecting metal ions' adsorption on these copolymers, such as pH, metal ion concentration, types of starch derivatives, treatment time and temperature was premarily studied at first.
