PtCl62- Bound PVP Modified Electrode in Catalytic Oxidation of Fe2+
Abstract:
The electrode coated with PVP (polyvinyl-pyridine) film electrostatically bound has been studied by means of cyclic voltammetry.The results showed that the electrode has a good electrocatalytic activity in the oxidation of Fe2+ to Fe3+ in aqueous acidic solution.The rate-controlling step and the kinetic parameters of catalytic reaction were determined by rotating disk electrode coated with PVP electrostatically bound PtCl62-.The rateconstant of the catalvtic reaction was calculated to be 5.67×106cm3·mol-1·s-1.The number of electron transfered and the anodic transfer coeffcient were determined.The electrode coated with promoted PVP electrostatically bound PtCl62- give very stable response for the oxidation of Fe2+ to Fe3+.
