Abstract
It was demonstrated that acridinium cation does not interact directly with copper electrode surface in acid sulfate solution. In the presenc e of chloride, acridinium cation adsorbed on the electrode as an ion p air with chloride anion. In the whole potential range investigated, fr om 0 V to a chloride desorption potential at about -0.6 V, acridinium did not undergo any redox-process. By shifting a potential towards neg ative values acridinium tends to reorient to a position perpendicular to the electrode plane. The formation of the ion pair stabilized chlor ide adsorption on the electrode surface.
