摘　　要：将高纯Ｅｕ２Ｏ２通过Ｐ５０７萃淋树脂分离富集，分离掉大量基体ＥＵ２Ｏ３，剩下微量稀土杂质用碳粉吸附，加ＫＢＨ４作载体进行光谱测定。本方法可测定９９．９９９９％纯度的Ｅｕ２Ｏ３中微量稀土杂质。The determination of trace rare earth impurities in high purity europium oxide by chemical spectrographic method is reported in this paper. The matrix Eu2O3 was separated by the extraction-eluting resin P507. The remainder rare earth impurities were absorpted by car- bon powder. The rare earth impurities absorpted were determined in carrier KBH4 by spec- trographic analysis. The trace rare earth impurities in 99. 9999 % Eu2O3 can be determined by this method.
