SIMULATION OF ELECTROCHEMICAL IMPEDANCE SPECTRA OF AMALGAM ELECTRODESIN CONTACT WITH MIXED ELECTROLYTE-SOLUTIONS CONTAINING ELECTROACTIVE CATIONS

The theory of the electrochemical impedance spectra developed earlier for the discharge of cations M+ adsorbed on the same metal M is extend ed to systems in which a liquid alloy Me-M plays the role of the elect rode. Diffusion of particles M, which are formed during the discharge, into the metal phase is taken into account. The modeling impedance sp ectra are calculated for the interface between Tl(Hg) and TlClO4 + 1 M NaClO4. The calculation is found to describe adequately the experimen tal curves obtained by Lorenz and Salie for this system.
