摘　　要：采用X射线荧光光谱测定Nd—Fe系稀土永磁合金中La，Ce，Pr，Nd，Fe，Co成份。该方法既能克服基体效应又能解决标准样品的制备问题，分析方法简便、快速、准确。对于体系较复杂的Nd—Fe系稀土永磁合金，采用本方法RSD小于2％，方法的加标回收率97％-105．8％之间。La Ce Pr Nd Fe Co concentrations in Nd- Fe rare earth permanent magnetism alloy were determined by X- ray fluorescence spectrometry. The method can eliminate the matrix effects and the problem of sample preparing, and it is simple, rapid and accurate. The RSD is less than 2%, and recoveries are between 97% - 105.8%.
