Abstract

Systematic studies of different methods for decomposition of samples of dead automobile catalyzers (ACs) on a ceramic base using mixtures of mineral acids and high-temperature alloying with the aim of subsequent determination of platinum, palladium, and rhodium using atomic emission spectrometry with inductively coupled plasma are presented. The behavior of matrix components of dead ACs under the conditions of sample decomposition is investigated. The effect of the results of determining platinum group metals is studied. The relative standard deviation of the results of the analysis performed according to the developed techniques is 11-9% at platinum, palladium, and rhodium concentrations ranging from 0.01 to 0.3%.
