对钴溶液中镉、铜、锰、锌、铁等金属离子的阴离子交换－CL－P204萃取色谱法分离进行了研究．钴渣浸出液经适当处理后，用强碱性阴离子交换柱除去大部分镉．除镉料液以经0.5mol/L的NaAc溶液（pH4．0）转型的CL－P204萃淋树脂为固定相、pH2.5的氯乙酸－氯乙酸钠缓冲溶液（0.1mol／L）为流动相淋洗，使钴与其余金属离子达到有效分离．该法分离提取钻的效果好、操作简便，为湿法冶金工业中钴的回收提供了一种新方法． Anion-exchange-CL-P204 extraction of cadmium, copper, manganese, zinc, iron and other metal ions in cobalt solution was studied. After proper treatment of the cobalt slag leachate, most of the cadmium is removed with a strongly basic anion exchange column. Except for cadmium, the CL-P204 extraction resin transformed by 0.5mol / L NaAc solution (pH4.0) was used as the stationary phase, and a solution of sodium chloroacetate-sodium chloroacetate buffer solution (0.1mol / L) Phase leaching, cobalt and other metal ions to achieve effective separation. The method has the advantages of good extraction efficiency and simple operation, and provides a new method for the recovery of cobalt in the hydrometallurgy industry.
