Determination of Platinum Metals in Carbonaceous Mineral Raw Materials by Stripping Voltammetry

The paper considers the possibility of determining platinum metals in mineral raw materials by stripping voltammetry on a graphite electrode modified by metals. Stripping voltammetry method is characterized by low determination limit, wide intervals of determined content and high sensitivity. As a result of the research the conditions for the determination of gold, platinum and palladium by stripping voltammetry have been selected. The comparison of the results of gold, palladium and platinum determination by stripping voltammetry and atomic absorption is presented.
