摘要
将样品基体分离,分别提取轻稀土和重稀土,优选参测同位素,采用同位素稀释质谱法(IDMS)对高纯Eu_2O_3样品中的Ce、Nd、Sm、Dy、Er和Yb等6种微量杂质进行定值。
The separation method of Eu2O3 matrix is given. The sample Eu2O3 is reduced by zinc powder and RE3+ is separated from Eu2+ by high pressure ion-exchange chromatograph. The trace impurities of Ce ,Nd ,Sm ,Dy ,Er and Yb in high pure sample Eu2O3 is measured by isotope dilution mass spectrometry (IDMS).
