Abstract

Using the oscillovoltammetric method, we study the nature of the current and the character of reduction of aqueous ruthenium solutions in the presence of organic addends and without them. The process of reduction of Ru(IV) solutions exhibits an irreversible character and is preceded by a chemical reaction. The electrochemical reaction proceeds on the surface of the dropping mercury electrode. The catalytic action of organic reagents is not connected with the regeneration of depolarizer. Finally, we propose a scheme for the mechanism of onset of voltammetric catalytic hydrogen currents.
