摘　　要：采用P507溶剂萃取深度净化镍电解液,得到符合镍电解工艺要求的低钴电解液和富钴溶液。利用离心萃取器,在流量1 L/h,相比(Vo/Va)=2/1,离心转速4000 r/min,水相料液pH=5.0的最佳条件下,用P507从镍电解液中萃取钴,钴萃取率为92.56%,钴、镍分离系数为4 353。离心萃取器可以作为镍钴高效分离设备,有良好的工业应用前景。The nickel electrolyte of low concentration cobalt and solution of richness cobalt can be obtained by purifying nickel electrolyte by solvent extraction with P507. By centrifugal extractor, under the condations of 1 L/h of flow volume, 2/1 of phase rate,4000 r/min of centrifugal speed, 5.0 of water phase pH, the extraction of cobalt is 92.56% ,and separation coefficient of cobalt and nickel is 4353. The centrifugal extractor can use as a equipment to separate cobalt and nickel,and has a great future for industrical application.
