摘　　要：采用膜电解和化学净化方法分离镍基合金中的杂质元素,提纯金属镍。实验分别研究了除铁、铜、钴工艺条件以及电流密度、电解温度对膜电解过程的影响。In this paper, the nickel-alloy was purified by membrane electrolysis and chemical purification. The chemical purification parameters such as temperatue and reaction time that affect the process of deironlization, decopperization and decobaltization were investigated at first, then parameters such as density of current and temperature that affect mambrane electrolysis was studied later.

关 键 词：镍基合金 提纯 膜电解 化学净化
