x-射线荧光光谱法测定重整催化剂中铂、铕、铈

Determination of Pt, Eu, Ce in reforming catalyst by X-ray fluorescence spectrometry

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 ,建立了重整催化剂中铂、铕、铈含量的测定方法。测定铂、铕、铈的相对标准偏差依次为 :0 .5 9%、0 .72 %、0 .75 %。

A X ray fluorescence spectrometry was applied to determination of Pt, Eu and Ce in reforming catalyst. The standard samples were manually synthesized, and the powder pellets were used for sample preparation and the matrix effects were corrected by the experience coefficients. The results showed that the accuracy and precision of this method were satisfactory. The relative deviations for Pt?Eu and Ce were smaller than 1 %.
