| Abstract: | The intensity-modulated photocurrents (photoadmittance) and the electrochemical impedance of an anodically oxidized iron electrode
are studied in alkaline solutions containing the sulfide ion. The photooxidation of S2- proceeds via a stage of their adsorption. The concentration of S2- adsorbed on the surface decreases at a potential shift in the positive direction |
