摘要
本文采用萃取色谱法以Ｐ５０７萃淋树脂为固定相，以ＨＣｌ－ＮＨ４Ｃｌ体系为淋洗液，研究了高纯Ｅｒ２Ｏ３（９９．９９９％～９９．９９９９％）中稀土杂质和Ｅｒ基体的分离方法，并选择了富集方法和火花源质谱测定条件，达到了纯度为９９．９９９９％的超纯Ｅｒ２Ｏ３的分析要求。
The separation of rare earth impurities in high purity erbium oxide have been carried out with P507 extration chromatography. Hydrochloric acid-Ammonium chloride serves as eluant.The method of preconcentration and the determination condition of spark source mass spectrometry (SSMS) have been selected. The measured purity of erdium oxide is up to 99. 9999%.
