Abstract

A two-step reduction of Zn(II) ions at the dropping mercury electrode in 1 M NaClO<sub>4</sub>/0.001 M HClO<sub>4</sub> in the presence of <i>N</i>,<i>N'</i>-dialkylthioureas was examined in wide potential and frequency ranges, using the impedance method. The rate constant of the first electron transfer increases with increasing concentration of <i>N</i>,<i>N'</i>-dialkylthioureas, whereas that of the second electron transfer depends largely on the double layer effects, particularly, on the orientation of molecules on the electrode surface.
