铕是单—稀土中用途最广的元素之一,它在激光和发光材料中的地位日趋重要,因此寻求有效分离提纯铕的新方法的研究,具有重要的意义。常用的锌粉还原——碱度法,化学试剂耗量大且收率不高;P—204萃取—锌汞齐还原反萃法,反萃酸度大, Europium is one of the most widely used elements in single-rare earth. It plays an increasingly important role in lasers and luminescent materials. Therefore, it is of great significance to seek new methods for the effective separation and purification of europium. Commonly used zinc reduction - alkalinity method, the chemical reagent consumption and the yield is not high; P-204 extraction - zinc amalgam reduction stripping method, stripping acidity,
