AbstractThe mechanism of the electrochemical oxidation of I−and I2at the bright Pt and Au electrodes and at platinized Pt ‐ electrodes saturated with H2or O2, was investigated by voltammetric and adsorption measurements. I131was used for adsorption detection. I−is strongly adsorbed and electrochemically oxidized to IO−at the bright electrodes as a function of the anode potential, but relatively weak adsorption takes place at the platinized electrodes. I2shows an apparent desorption as a function of anode po
