摘　　要：通过对某公司的硫酸镍溶液的试验研究,采用P204做萃取剂进行液-液萃取分离Fe^(3+)、Zn^(2+)和Ni^(2+)的试验,Fe^(3+)萃取率>85%,反萃率达到90%;Zn^(2+)萃取率93%,反萃率在90%以上;Ni^(2+)基本不被萃取,回收率可达98%以上。通过对硫酸和盐酸的反萃小试结果对比,用P204做萃取剂盐酸反萃的三级连续萃取试验Fe^(3+)和Zn^(2+)的反萃率均>98%。Through the experimental study of nickel sulfate solution of a company,the liquid-liquid extraction of Fe^(3+)、Zn^(2+)and Ni^(2+)was caried out by using P204 as extractor.The extraction rate of Fe^(3+)was more than 85%,and the extraction rate reached 90%.The extraction rate of Zn^(2+)can be 93%,the reverse extraction rate is more than 90%,Ni^(2+)is basically not extracted,and the recovery rate can reach more than 98%.By comparing the results of the back-extraction test of sulfuric acid and hydrochloric acid,the three-stage continuous extraction test using P204 as extractant for back-extraction of Fe^(3+)and Zn^(2+)was more than 98%.
