| 摘 要： | 提出了微波密闭消解难处理贵金属合金PtW、PtRh、PtPdRh和PdIr、PtIr、PtIrRE、PtRuIr的方法;对比了它们的微波密闭消解和传统分解法的条件;分析了消解后贵金属Pt、Pd、RhI、r的含量。结果表明:上述各类合金对应消解时间分别为传统法的1/14~1/15和1/24~1/8倍;总分析流程大大缩短;两种方法测得贵金属结果相吻合。

| Abstract: | A new microwave-assisted closed digestion method for the decomposition of the precious method alloy of PtW, PtRh, PtPdRh and PdIr, PtIr, PtIrRe, PtRuIr was developed. Comparison of the dissolving conditions by the proposed method and the traditional meth- od were conducted. The contents of precious metals Pt, Pd, Rh, Ir were determined. The results show that digestion time of the alloy using the proposed method is 1/14- 1/15 and 1/24- 1/8 times than that by the traditional method. The analytical processes were greatly reduced. The contents of Pt, Pd, Rh and Ir were almost the same by two methods. |
