摘　　要：试验研究了电感偶合等离子体光谱仪的工作参数、分析条件、样品溶解等对测定的影响,共存元素、基体的干扰情况。以钇作内标,用HNO3、HF、HClO4处理样品,选择仪器最佳分析参数和分析条件,实现硅铝钡中Al、Ba、Fe、Ca、Mn、Cu、Cr、Ni、P等9种主次量元素成分的同时快速、准确的测定。Influences of operating parameters of ICP - AES, analytical conditions and sample dissoling on measurement as well as interference of matrix and coexist elements are studied by experiments. Y is used as internal element. By using HNO3, HF, HClO4 processing samples, choosing the optimal parameters of instrument, and the optimization condition, measuring Al,Ba,Fe,Ca,Mn,Cu,Cr,Ni,P of Si - Al - Ba alloy in the same time is realized. The method is rapider and more accurate.
