    摘要:

    分析了金属催化转化器在汽车行业的市场前景和行业管理现状。针对车用金属催化转化器样品,建立了用ICP-MS法测定催化剂涂层中贵金属Pt、Pd、Rh含量的方法。采用6 mol/L盐酸溶液浸泡样品,将得到的滤液与不溶物分别经过碲共沉淀制备成试液。经过8家实验室的共同验证:本方法对于Pt、Pd、Rh 3种元素,各试验室的样品测定结果与参考值的相对偏差均小于10%,再现性不确定度分别为:6.6%、6.5%、5.8%,本方法检出限低,回收率高,再现性好,可行性强

    Abstract:

    The market prospect and industry management of metal catalytic converters in the automotive industry was analyzed. For the automotive metal catalytic converter samples, a determination method for precious metal Pt, Pd and Rh using ICP-MS was established. After soaked in 6 mol/L HCl solution, the sample turned into filtrate and insoluble, and then they were prepared into test solutions separately after tellurium co-precipitation. The method was co-verified by eight laboratories, and the results are as following: for Pt, Pd and Rh, the relative deviations between the determination results and the corresponding reference values are all less than 10%, and the reproducibility uncertainties are 6.6%, 6.5% and 5.8%, respectively. It is concluded that the method has low detection limits, high recoveries, good reproducibility and satisfactory feasibility
