摘要
试样的消解方法是样品分析预处理的研究热点之一。针对汽车催化剂中铂族金属(主要是铂、钯、铑)的预处理和检测问题,归纳总结了催化剂试样的消解方法(主要是酸溶法、碱熔融法、火试金法),阐述其利弊,为分析和测试铂族金属选择适宜的试样预处理方法,并对其今后的发展进行了展望。
Digestion method of samples is one of hot research for pre - treatment of sample analysis. For the problems of pre - treatment and analysis of using platinum - group metals （ mainly platinum, palladium, rhodium） as automotive catalysts, the catalyst sample digestion methods （mainly aciddissolution method, alkali melting method and fire assay） are summarized, and its advantages and disadvantages are discussed, what can help choose suitable method of sample pre - treatment for the analysis and testing of platinum - group metals. At last, its future development is prospected.
