根据目前市场需求，设计了废汽车尾气净化催化剂分析用标准样品的组成及特性值Pt、Pd、Rh 含量范围，建立了标准样品的制备工艺流程，对制备的标准样品进行了均匀性和稳定性检验、定值分析及量值溯源。经检验，均匀性符合要求；经t检验，在正常的保存条件下样品是稳定的。采用ICP-AES法、分光光度法及火焰原子吸收光谱法对样品进行协作定值，确定了Pt、Pd、Rh的标准特性值并对其不确定度进行了评估。制备得到的标准样品，可作为废汽车尾气净化催化剂分析过程中仪器校准、测量方法评价、人员培训或给其它材料赋值等诸项工作提供依据。

The composition and the property values of Pt, Pd, Rh for waste autocatalysts were designed based on the current market demand. The process flow for reference material development, and the homogeneity and stability were tested in present study. Characterization analysis and value traceability are made for the materials prepared. According to variance analysis, the materials are homogeneous for Pt, Pd, Rh.t-testing results indicated that the well-prepared samples stored under the normal conditions are stable. The samples are collaboratively certified by ICP-AES, spectrophotometry and flame atomic absorption spectrometry. The certified values for Pt, Pd, Rh are obtained, and the uncertainty for Pt, Pd, Rh are evaluated. The reference material provides a basis for calibrating the instruments, evaluating measurement methods, training Staff or assigning to other materials.
