Analysis of platinum group elements (PGE) extracted from various catalysts used in the car, petroleum and chemical industries requires use of microanalytical methods. PGE content in the platinum powder concentrates K176 and K177 was studied by SEM-EDS. The content of main elements was determined using analytical lines Fe Kα1, Si Kα1, Sn Lα1, Pt Lα1, Re Lα1. The obtained data for the chemical composition are in good agreement with the result obtained by X-ray fluorescence analysis and ICP-MS method. Powdered platinum concentrates are considered to be ferrosilicide (FeSi), where PGE are localized at the phase boundaries and in separate patches of the K176 sample, or distributed over the volume of particles in the K177 sample.

AbstractThis paper describes the determination of the individual platinum-group elements by X-ray fluorescence after nickel-sulphide fire-assay collection. The platinum-group sulphide residue obtained after the dissolution of the nickel is dissolved in acid, and reduced to the metal by use of sodium borohydride. The finely divided metals are then filtered onto a millipore filter, and measured by X-ray fluorescence spectroscopy. The procedure makes use of gold as an internal standard. Factors affecting the accuracy and precision are investigated.
