摘要：

Parabanic acid reduction has been studied in low acidity x M HCl + (2 - x)M LiCl mixtures by the faradaic impedance method. The overall reaction obeys an electrochemical scheme with a quasi-reversible electron transfer, a coupled homogeneous following reaction and weakly adsorbed reactant and products; the reaction is further complicated by the presence of a polarographic maximum. Analysis of the electrode admittance over an extended potential range (about 1 V) allowed the determination of the electron transfer and adsorption parameters.
