摘要
以Ｐ_（５０７）萃淋树脂为固定相，ＨＣｌ－ＮＨ４Ｃｌ为淋洗液，研究了９９．９９９％～９９．９９９９％高纯Ｄｙ２Ｏ３中痕量稀土与基体Ｄｙ的分离法，以及火花源质谱法的测定条件。可分析９９．９９９９％超高纯Ｄｙ２Ｏ３中痕量稀土杂质，测定限０．００１～０．１×１０－６，误差３０％。
Method for concentration of rare earth impurities in extra-pure Dy2O3 has been studied by P507 extract ion chromatography using P507 extractive resin as stat ionary phase and HCl-NH4Cl as eluent.Conditions for their spark source mass spectrometric determination were also studied.
