Abstract:

The occurrence of a catalytic effect in polarography was first discovered by Wiesner.The effect involves the regeneration of the reactant by the addition of a powerful oxidizing agent to the analyte solution. This regeneration will increase the concentration of the reactant around the electrode, thereby giving a larger current response. So far the hydrogen catalytic waves of protein and the catalytic wave of inorganic ions have been extensively investigated. Besides the hydrogen catalytic wave of protein, Catalytic effect for organic compounds are rare.
