Variations of the charge and open-circuit potential during the ion adsorption with the formation of irreversibly adsorbed atoms

The transients of the current and open-circuit potential (OCP) for the B^z± ± ze → B_ad process, where B_ad is an irreversibly adsorbed atom, are described analytically. The analysis is based on the earlier obtained relationships for variations in the total charge and OCP of a hydrogen electrode during the irreversible adsorption of neutral species. A graphic method of estimating the OCP shifts and integral current transients (E^ads = const) corresponding to various surface coverages with B_ad is proposed. Dedicated to the ninetieth anniversary of Ya.M. Kolotyrkin’s birth.
