The parameters of the electrodes, such as their areas, positions, and the distance between the anode and cathode were optimized for the electrolytic reduction process. By the optimal process, the product YbSO4 is purified to 99.5% with recovery of 80%. Meanwhile, Lu is also concentrated into 50%, which is beneficial to its further purification. 关 键 词：电化学 电极 镱 铥 镥 电解工艺 硫酸盐 稀土
