title: Investigation of the electroreduction of silver sulfite complexes by means of electrochemical FFT impedance spectroscopy.
abstract: The electroreduction kinetics of silver sulfite complexes was investigated by electrochemical fast Fourier transform (FFT) impedance spectroscopy (0.061-1500 Hz). The time dependences of the real and imaginary components of impedance were determined in a solution containing 0.05 M Ag (I) and 1M Na(2)SO(3). The mean duration of silver ad-atom diffusion on the surface to the nearest crystallization centre was calculated: during the first 210 s of contact with the electrolyte, these values increase from 0.66 up to 1.77 s; thereafter, this variation stabilizes and the mean duration of silver ad-atom diffusion reaches an almost constant value (1.56 s).
