摘　　要：综述1990以来国内外采用协同萃取方法从复杂溶液中分离钴和镍的研究现状。将钴和镍协萃体系分为螯合萃取剂有机酸体系、有机磷酸类混合体系、吡啶羧酸酯有机酸类体系和胺类有机酸类体系4类,分别介绍这些协萃体系对钴、镍及其他金属离子的分离情况及萃取机理,对相同类型的体系进行比较,分析各协萃体系的分离特点,并提出运用协萃体系需要进一步解决的问题。The synergistic solvent extraction of cobalt and nickel from complex solution at home and abroad was summarized since the 1990s. The system of synergistic extraction is divided into four categories, including chelating extractant and organic acid, organophosphorous class of hybrid, pyridinecarboxylate esters and organic acids, and amines and organic acids. The separation and extraction mechanisms of different extraction systems were introduced, respectively. And the characteristics of synergistic extraction were analyzed by comparing the same synergistic extraction system. Finally, some problems about the synergistic extraction system that should be further studied were proposed.
