| Abstract: | ICP MS technique was applied to the analysis of non RE impurities (Al, Fe, Ni, Ti, Co, Cd, Mn, Pb, Cu, Ba, Mg) in dysprosium metal without matrix separation. Limits of determination were estimated and the effect of acidity. The comparison experiments among flame atomic absorption spectrophotometric method, photometric method and ICP MS method were made. With In asan internal standard, the recovery of this method was from 80.5% to 110.2%, and RSD was below 12%. |
