Abstract

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).
