摘　　要：用Ｎ２３５＋ＴＢＰ作萃取剂，Ｈ２Ｏ作反萃剂从大洋多金属结核盐酸浸出液除铁余液中萃取钴。ＨＣｌ浓度、Ｃｌ－浓度、Ｎ２３５浓度、相比对钴的萃取率有较大影响，而萃取时间则无明显影响。模拟试验结果表明，当平衡次数为１７～２１次时，钴的萃取率大于９７７％，反萃率大于９８％。Extraction of cobalt from HCl leaching liquid of ocean polymetallic nodules using N235 as extractant and H2O as stripping agent was studied. Apart from extraction time, the other parameters, suchas concentrations of HCl, Cl- and N235 and phase ratio have greater influence on the extraction ratio of cobalt. Its simulated test showed that at equilibrium times of 17～21, the extraction ratio of cobalt is higher than 977% and the stripping ratio of cobalt is higher than 98%.
