Comparative Characteristics of Voltammetric Methods Determination of Platinum in Mineral Raw Materials

Abstract:

The technique of platinum (IV) determination in mineral raw materials with the application of stripping voltammetry has been proposed. The authors determined the registration conditions in the determination of the analytical signal Pt (IV): the composition of background electrolyte, the electrolysis potential. The graphite electrode impregnated with polyethylene was used as a working electrode. The use of stripping voltammetry applied to the assessment of the platinum content in geological objects was demonstrated.
