A New Method on Fabrication of a Cobalt Hexacyanoferrate Modified Glassy Carbon Electrode and Electrocatalytic Reaction of Dopamine There on
Abstract:
A new method on fabrication of cobalt hexacyanoferrate modified glassy carbon (CoHCF/GC) electrode is described.The method is easy to manipulate and control the coverage of CoHCF on the surface of the GC electrode.The CoHCF/GC electrode shows electrocatalytic activity towards the redox reaction of dopamine (DA) in the phosphate buffer solution with a decreasing of the overpotential of 140 mV.The reaction rate constant of the dopamine oxidation at the CoHCF/GC electrode is determined with rotating disk electrode measurements.
