铝锌系列变形铝合金的X射线荧光光谱分析

Analysis of Wrought Aluminium Alloy by X-Ray Fluorescence Spectrometry

介绍了采用射线荧光法测定铝锌系列铝合金中各元素含量的方法及相关条件,以俄罗斯ВИЛС公司研制的Al-Zn-Mg-Cu系列铝合金标准物质作为光谱标准,基体效应校正采用基本参数法,建立了X射线光谱测定铝锌系列变形铝合金中Cu、Mn、Mg、Fe、Si、Zn、Ni、Cr、Ti和Zr10种元素的方法。该方法分析实际样品,结果和化学法分析值相吻合,10次制样测量,各元素RSD在0.18%～3.08%。本方法具有样品前期处理简便、干扰因素小,且快速、准确等特点。

The method and related conditions of determining the elements contents in aluminium-zinc series wrought aluminium alloy by ray flu- orescence spectrometry is described. The X-ray fluorescence spectrometry method has been developed for the determination of ten elements （Cu, Mn, Fe, Si, Zn, Ni, Cr, Ti and Zr） in aluminium-zinc series wrought aluminium alloy with using Al-Zn-Mg-Cu series al series alloy as stan- dard samples which is from Russia BPI）IC Company. The matrix effect is corrected by fundamental parameter method. The results are in agreement with those from chemical method with a RSD of 0.18%-3.08% （n=10）. This method has many advantages, such as simple pretreatment, little distur- bances, rapid and accurate, etc.
