摘　　要：建立了采用V（HNO3）：V（HClO4）=15：2作消解液进行溶样，ICP-AES法同时测定滑子蘑中Cd、Cu、Pb、Zn的分析方法，进行了ICP工作参数的优化，消解条件的选择及消解结果精密度实验。在最佳测定条件下，4种元素标准曲线相关性好（r为0．9990—0．9995），线性范围宽，精密度RSD为0．4％-4．6％，样品加标回收率为91．0％-101．0％，已用于实际样品的测定。In this paper, a method of inductively coupled plasma atomatic emission spectrometry （ICP-AES） for the subsequent determination of Cd, Cu, Pb, Zn was developed. The digestive solution was a mixture of perehloric acidnitric acid （15：2, volume ratio）. The working parameters and the digestive conditions were chosen. Under the optimum conditions, the correlation coefficient of four elements were 0. 9990 - 0. 9995, the RSDs were 0.4% - 4.6%, and the recoveries were from 91.0% to 101.0%, The results were satisfactory in the pratical samples. The method is fast, simple for simultaneous determination of several elements.
