摘要：

The two-step reduction of Zn(II) ions at a dropping mercury electrode in 1 M NaClO4/0.001 M HClO4 in the presence of thiourea was examined in wide potential and frequency ranges using the impedance method. The catalytic activity of thiourea concerns both electron transfer steps. It was found that the acceleration of the electroreduction process depends on the surface concentration of thiourea.
