Theory of kinetically controlled electrode reaction coupled to ion transfer across the liquid / liquid interface

An electron transfer reaction at graphite electrode that is covered by a thin film of organic solvent, which is immiscible with water, and immersed into an aqueous electrolyte is considered theoretically. The redox couple is confined within the film and the conductivity is achieved by the transfer of anion of supporting electrolyte across the organic solvent / water interface. In linear scan voltammetry the peak potential depends on the initial concentration of either reactant, or the anion of supporting electrolyte in the film. A critical value of dimensionless kinetic parameter, which can be used for the determination of standard rate constant, is calculated.
