| Abstract: | Platinum,palladium and gold in Sample was enriched by fire assay method,and the precious metals alloy obtained was dissolved by nitric acid （1 ＋ 1 ） and hydrochloric acid,The contents of platinum palladium and gold in the sample solution were determined by ICP-MS. The proposed method was used in the analysis of CRMs, precision and accuracy of the results meet the requirements of the standard. |
