Sažetak
A fast and simple method for the estimation of kinetic parameters of surface redox reactions, based on the splitting of their square-wave voltammograms, is proposed. A mathematical procedure for simulation of these processes is developed. The method can be applied for the fast and chemically reversible redox reactions which are characterized by the kinetic parameter K 0.8 (K = ks/f). The standard rate constant, transfer coefficient and standard redox potential of the redox reaction of alizarine-red S adsorbed on the mercury electrode in pH 9 medium are ks = 60/s and alfa = 0.45 and E0 = -0.810 V (vs Ag/AgCl-KCl).
