摘　　要：采用碳化裂解-HNO3-HClO4消解法处理鞋材样品，用ICP-AES法在同一份制备液中同时测定鞋材中Pb，CA，Cr，Ni，Cu，Zn，Co，Fe等多种重金属元素含量。对分析谱线的选择，基体和共存元素的干扰情况等进行了研究，方法安全、简便、快速、准确。回收率在92．0％～102．0％之间，相对标准偏差在1.0％～4．6％之间。Footwear materials were treated by the digestion method of carbonization-crack-HNO3-HClO4 dissolution, and the heavy metal elements in these materials were simultaneously determined in the same treated solution. Factors such as the selection of analytical wavelength and the interference of matrix and coexistent elements were studied. The method was secure, convenient, rapid and accurate. The recovery rates of the procedure were between 92. 0% and 102.0% with RSDs between 1.0% and 4. 6%.
