| Abstract: | Foureteen kinds of trace rare-earth impurity is separated from high--pure lutetium oxideby means of P507 extraction and elution resin that is in hydrochloride acid system. The content of each impurity can be determined by ICP--AES. The testing limit is low, the anti--interference ability is high. The period of separation is short, and the stability of the method isgood. The operations have been done several times. The recovery rates for these impuritiesare from 81. 4 percent to 116 percent and the relative standard deviations are from 1. 68 percent to 6. 0 percent. |
