摘　　要：研究了在硫酸体系中采用电解还原法将镱从铥、镱、镥的混合物中分离出来的过程中 ,各种因素—包括阳极液酸度、阴极液酸度、槽压、料液浓度、搅拌速度等对电解还原效果的影响和阴极液中SO2 -4 浓度对Yb2 + 沉淀的影响。Several factors(acidity of catholyte, acidity of anolyte, voltage, concentration of Yb 3+ , stirring speed) to influence of electrolyze reduction in the process of separating Ytterbium from the mixture of Tm, Yb and Lu by method of electrolyze reduction in H 2SO 4 system and concentration of SO 2- 4 to influence of depositing Yb 2+ were studied.
