Results indicate that EO(SHE) tends to decrease a little with the increasing solvent permittivity probably due to a stabilization of the oxidized ferrocene form by its interaction with polar solvent molecules. Estimated values of EO(SHE) and An electrode voltammetry of DMFc are then used to calibrate the potential of the bis(triphenylphosphoranylidene)ammonium(+) (BTPPA(+)) ion-selective type reference electrode (RE), which has been often employed in polarization studies at the interface between two immiscible electrolyte solutions.
