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.
