摘　　要：建立了X射线荧光光谱法无标样分析测定催化剂中主次量元素的方法。用熔融制样法将粉状催化剂制成玻片,应用UniQuant无标分析软件对其中的Al,Si,Gr,Ce,La等元素的含量进行了检测。测定结果的相对标准偏差(RSD,n=9)在0.11%~1.9%之间。通过与化学法测定结果比对,数据吻合良好。A method was established for the determination of the major and minor elements content in the catalyst by the method of X-ray fluorescence spectrometry without sample analysis in this paper. Firstly, the powder catalyst will be molten into glass samples. Then metal content will be tested, such as aluminum, silicon, zirconium, cerium, and lanthanum elements by the software UniQuant without standard sample analysis. The determination results of relative standard deviation （RSD, n = 9） was from 0. 11% to 1.9%. Finally the results were coincided with the chemical analysis method.
