Coupled Radiometric and Electrochemical Study of the Reduction of Tco4- Ions at a Gold Electrode in Acidic Medium (Mechanistic Aspects of Tc Deposition)
The reduction of TcO4- ions at a smooth gold electrode was studied in 1 mol dm-3 H2SO4 supporting electrolyte using coupled voltammetric and volt-radiometric measurements and steady state measurements. The problems of the existence of parallel pathways leading to the formation of a Tc layer and dissolved Tc(IV) complexes are discussed. A general scheme is suggested for the interpretation of the phenomena.
