By using Randles equivalent circuit, the kinetic factors on electrode reaction between the alloy and the salt were obtained, such as electrolyte resistance Re, double-layer capacitance Cd, charge transfer resistance Rct, rate constant of desulfurization reaction Kf and so on. When overpotential η equals to -85 mV, these values are Re=2.93×10-5 Ω.m2, Rct =2.47×10-5 Ω.m2, Cd=1.01 F/m2, Kf=2.1 × 10-3 s-1, respectively.
