A method for the separation and determination of Pt, Au and Pd in various geological materials by coprecipitation with tellurium and applying two spectrometric methods was considered in detail. Particular attention was paid to the influence of matrix elements on the determination of these metals. In one instance the metals were determined in solution by applying a U-shaped arc stabilized by an argon vortex and in the other in the solid sample by applying a vertical arc burning in a stream of a'rgon-oxygen. The accuracy of the method was verified using the international reference standard SARM-7, and the results achieved were compared with published data.
