摘要：

The Fe3+ reduction reaction was studied at Pt and polyaniline rotating disk electrodes by steady-state and impedance methods with the aim of testing the possibility of achieving the charge transfer resistance (R(ts)) of a redox reaction mediated by a conducting polymer film by ac impedance. R(ts) was obtained as a function of electrode potential and rotation rate by nonlinear least squares fitting of a previously developed kinetic equation to the experimental data. These R(ts) values were combined with steady-state ones to calculate b(c) and K(o).
