摘　　要：使用X射线荧光光谱仪,采用人工合成标样,粉末直接压片和经验系数校正基体效应的方法,建立了助催化剂中磷和铁含量的测定方法。测定范围磷为0.01%～2.50%,铁为0.01%～2.50%。该方法不仅快速、简便,而且准确度和精密度较好,测定磷和铁的相对标准偏差依次为:0.34%、0.59%;满足了科研和工业生产的需要。X-ray fluorescence spectrometry was applied to determination of P and Fe in cocatalyst.The standard samples were manually synthesized,and the granules were used for sample preparation and the matrix effects were corrected by the experience coefficients.The determination ranges given by the method were as follows :P 0.01 %～2.5 %,Fe 0.01 %～2.5 %.The relative deviations for P and Fe were 0.34 % and 0.59 %.The results show that the accuracy and precision of this method are satisfactory.
