Analysis of voltammograms, chronoamperograms and electrochemical impedance spectra (0.05÷4000 Hz) indicate a slow stage of chemisorption of sulfite ions that reduces an active surface of gold electrode, and significantly influences a parallel stage of charge transfer of gold(I)-sulfite complexes. The proposed equivalent circuit representing electrochemical process well fits to experimental dependencies of real and imaginary parts of impedance on frequency. Values of elements of equivalent circuit at different potentials of gold electrode (0.1÷-0.5 V) were calculated. Cathodic voltammogram simulated by using the dependencies of elements of equivalent circuit on electrode potential rather well represents experimentally obtained voltammograms.
