摘　　要：用国产羟肟类萃取剂Ｎ５３０（２－羟基－４－仲辛氧基二苯甲酮肟）除去镍电解液中的铜，在ｐＨ４．０，单级萃取，奉取时间 ３ｍｉｎ，除铜率达 ９９．７％，而对 Ｎｉ２＋萃取极少，Ｃｕ／Ｎｉ分离系数达 １０６以上，萃取剂经再生，１０％Ｎ５３０可循环使用４次。N530 (2-hydroxy-4-sec-octanoyl-diphenyl-ketoxime) was used as extractant to remove Cu2 + from nickel electrolyte in which one-stage extraction of Cu2 was carried out for 3 minutes with pH 4. 0, resulting in the extraction rate of 99.7% for Cu2+ with an extremely tow amount of Ni2 + being extracted at the same time. The separation coefficient of Cu2 + to Ni2 + was up to 106. By regeneration, 10 % N530 can be used for another 4 times, and 20% N530 for another 7 times.
