摘　　要：以西南铝业公司研制的E223系列ZL205A铝合金作为光谱标样,用干扰曲线法结合理论α系数对谱线重叠干扰及基体效应进行校正,建立了X射线荧光光谱测定铸造铝合金ZL205A中除B外的Mg、Si、Ti、V、Mn、Fe、Cu、Zn、Zr和Cd10种元素的方法。该方法用于实际样品分析,结果与化学法、原子吸收法相吻合。10次制样测量,各元素RSD在0.42%～2.23%。A Xray fluorescence spectrometric method has been developed for the determination of ten elements except for boron in ZL205A alloy of E223 series of standard samples from China Southwest Aluminium Co. The interferences from line overlap and the interelement effect are corrected by using the interfering curve method and the theoretical alpha coefficient. The method has the advantages of rapid and reliable. The results are in agreement with those from AAS and chemical method with precision of 0.42%～2.23% RSD (n=10).
