摘　　要：本文对钴与锌、镉等金属离子的阴离子交换色谱法分离进行了研究．采用201×7型阴离子交换树脂经氧化铵溶液饱和后，在pH＝4．0时，使钴与其它金属离子分离，然后分别用0．02mol／L的盐酸溶液及蒸馏水将锌、镉等金属离子从阴离子交换树脂上洗脱．此法分离效果好，操作简单方便．In this paper, anion-exchange chromatography by which Co2+ can be separated from Zn2+. Cd2+ was described. The chromatographic column consisted of anion resin 201×7was saturated by the solution of ammonia chloride. The effect of the eluent acidity and eluent composition were investigated. The results show that when the column is saturated with pH4.0NH4Cl(2.0mol/L),the separation can be completed effectively and that this anion-exchange chromatographic method is suitable for sepime Co2+ from Zn2+' Cd2+,and the condition and operation of separaion is simple and convenient.
