摘　　要：利用ICP-MS测定镀锌板镀层中铅、镉、铬的含量。对ICP-MS测定条件进行了最佳化的选择,利用在线内标等技术,可降低基体干扰,直接检测元素的含量,方法的检出限为1.53～36.3μg/L,回收率为82.4%～94.5%。A method for the determination of Pb,Cd,Cr in galvanized plate coating have been developed by ICP-MS.Using on-line internal standard technology,the experimental conditions of ICP-MS were optimized.The matrix interference was reduced and sensitivity was improved.The detection limits and recoveries of the method are in the range of 1.53～36.3 μg/L and 82.4%～94.5% respectively.
