Applying impedance spectrum technique to liquid/liquid interfacial electrochemistry, we present the theoretical expression of the liquid/liquid interfacial impedance in the four-electrode electrolytic cell measured by alternating current impedance method. The influence of the electrolytic cell parameters and input passage parameters of the impedance apparatus on impedance spectrum curves are theoretically studied.
