| Abstract: | 2-ethylhexanoate-2-ethylhexyl phosphonate extraction chromatography was used to separate l4 rare earth impurities from ultra-pure Tm2O3, Yb2O3 and Lu2O3 and then the impurities were determined by atomic emission spectrometry. The recovery for each element is 72% -128%. The relative standard deviation of the determination is 5. 1%-23. 2. This method can be applied to the determination of trace amounts of rare earth impurities in 99. 9999 %-99. 99999 % Tm2O3,Yb2O3 and Lu2O3. |
