摘　　要：采用电解的方法将三价铕还原成二价。本文主要考察了电极材料、电流密度、阴极液酸度及料液初始温度对还原效果的影响。还原后接碱度法 ,制得大于 99.95 %的氧化铕产品。It is to reduce Eu 3+ into Eu 2+ with electrolyzation method.This article mainly describes the influences on the reduction results,such as:the electrode material ,electric current density,acidity of cathode liquor and initial temperature of feed liquid.After reduction,Eu 2O 3 with concentration of more than 99.95% can be generated with alkalinity method.
