摘　　要：采用N910萃取剂对铜镍溶液萃取分离铜(Ⅱ),考察了水相初始的pH值,萃取剂浓度,萃取震荡时间和相比对铜镍萃取率的影响。结果表明:在pH=6.00,萃取剂浓度为1%,萃取时间3 min,相比为3∶5时,铜(Ⅱ)的萃取率可达100%,萃取液中镍(Ⅱ)含量为0,达到分离要求。Using N910 reagent as extractant for separating Cu（Ⅱ） from copper-nickel solution was researched in this paper.The effects of pH value,extractant concentration,vibrating time and phase ratio on extraction rate of Cu（Ⅱ） were examined.The results indicate that the extraction rate of Cu（Ⅱ） can reach to 100%,and Ni（Ⅱ） content in the Cu（Ⅱ） stripping liquor was 0 when pH was 6.00,extractant concentration was 1%,extraction time was 3min and phase ratio was 3：5,reaching the separation requirements.
