FIELD: metallurgy.
SUBSTANCE: invention is aimed at determination of palladium in ore by stripping voltammetry and can be used in hydrometallurgy, in different geological mines when searching for and prospecting in case of analysis of ores, ore concentrates and rocks of concentration of ions of palladium. Method of determining palladium in ore by stripping voltammetry consists in fact that palladium (II) is changed into solution and voltammetric determination of concentration of palladium (II), wherein palladium are transferred in solution in chloride complex and determining concentration of palladium (II) ions on graphite electrode in stirred solution at controlled potential of minus 0.8 V and detecting signal on background electrolyte of 0.1 M HCl, relative saturated silver chloride electrode by standard addition method.
EFFECT: invention provides lower limit and lower bound of determined content of palladium (II).
