【Abstract】 X-ray fluorescence spectrometric analysis ofmixed rare earth oxides and highly pure rareearth oxides are studied in the paper. SOme mainfactors which influence the accuracy and the pre-cision in macro analysis are investigated includingsample and standard preparation and correctionof the matrix effects.The methods of loweringthe determination limit in trace analysis are alsoresearched,which include choosing the best mea-surement conditions,lowering background andthe method of separation and concentration更多还原
