汽车尾气净化催化剂中铂、钯和铑的测定

Determination of Pt, Pd and Rh in Automobile Catalyst

贵金属是汽车催化剂中的主要活性组分,准确测定汽车催化剂中Pt、Pd、Rh含量对控制催化剂的成本和保证催化性能,以及从失效催化剂中回收贵金属都具有重要的意义。本文详细介绍了汽车尾气催化剂分析中的取样、制样、溶样及分析方法。

Precious metals are the most active component in the automobile catalyst. Accurate determination of Pt, Pd and Rh is important for controlling the cost of catalyst, ensuring the performance of catalyst and the recovery from exhausted catalyst. The sampling, dissolution and analysis methods of automobile catalyst were introduced.
