| 摘 要： | 本文介绍了高纯氧化镧中微量稀土杂质的化学光谱测定，将Ｌａ２Ｏ３通过Ｐ５０７萃淋树脂分离富集，将大量基体分离掉，剩下微量的稀土杂质，用Ｃ粉吸附后加ＫＢＨ４做载体进行光谱测定。本方法可测定９９．９９９９％纯度的Ｌａ２Ｏ３中的微量稀土杂质。

| Abstract: | The determination of trace rare earth impurities in the high-purity Lanthanum oxide by chemical spectrographic analysis is reported in this paped. The matrix, La2O3, was separated by the extraction-eluating resin P507. The remained rare earth impurities were absorpted by carbon powder. The rare earth impurities absorpted were determinated in carrier KBH4 by spectrographic analysis. The trace rare earth impurities in 99.9999% La2O3 can be determinated by this method. |
