Abstract

The effect of hydrogen on the electrooxidation current of a palladium–hydrogen precipitate is studied. It is shown that the UV irradiation of the solution changes the mechanism of the formation of molecular hydrogen in the electrochemical deposition of palladium. A procedure is developed for determining palladium in platinum metal preconcentrates by stripping voltammetry.
