Abstract: The electrochemical behavior of benzyl viologen bication (BV2+) on glassy carbn (GC) electrode in phosphate buffer (pH=6.8) was studied by cyclic voltammetry.The redox process of BV2+ on unactivated GCelectrodes depends strongly on the concentration of BV2+, potential range and scan rates.BV2+ ions are reduced in two steps, the neutral viologen deposited on the electrode.On electrochemically activated GCelectrode the adsorption of BV2+ is greatlyenhanced, and only adsorbed BV2+ shows its redox process in the dilute BV2+ solution, however, the adsorbed BV2+and BV2+ in the solution take part in the electrode process in the concentrated solution.The possible effect of electrochemical activation of GCelectrode was discussed.
