本文采用萃取色谱法，以Ｐ５０７萃淋树脂为固定相，以ＨＣｌ－ＮＨ４Ｃｌ体系为洗脱液，研究了９９．９９９％～９９．９９９９％高纯Ｇｄ２Ｏ３中稀土杂质和Ｇｄ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％的高纯Ｇｄ２Ｏ３的分析测定要求
In this paper, the separation method of rare earth impurities and Gd matrix in 99.999% -99.9999% high purity Gd2O3 was studied by using P507 extraction resin as stationary phase and using HCl-NH4Cl as eluent. The method of enrichment and determination of spark source mass spectrometry were selected and the analytical determination of high purity Gd2O3 with the purity of 99.9999%
