The effects of thiourea on the mechanism of the Cu/Ct?+ system were studied using Pt/Pt and Cu/Pt rotating ring disc electrodes in a 0.7 M CuS04-1.8 M H,SO, solution. Thiourea at low concentrations inhibits the reduction of the intermediate Cu+ to Cu on a copper surface. Thus more Cu+ escapes from t
