Fourier Analysis of Alternating Current Polarography: Amplitude and Phase of Fundamental and Second Harmonic AC Polarographic Waves

The Fourier analysis of the instantaneous AC polarographic current was performed with a computer on-lined to a potentiostat. From the Fourier spectra, the amplitudes and phase angles of both the fundamental and the second harmonic AC polarographic waves were obtained. In the Cd(II) system, the current amplitude DC potential curves and phase angle-DC potential curves for the fundamental and the second harmonic AC polarographic waves were compared with the theoretical curves. The method is applicable to the accurate analysis of electrode reaction kinetics.
