The kinetics of the displacement (cementation) of gold by a rotating mild steel disc from an acidic thiourea solution are described. By measuring the rate of loss of gold as a function of time, it was established that the rate of the reaction was first order with respect to the gold concentration.
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
The evolution of the surface roughness during cementation of Ag + conducted either in O 2 -free or O 2saturated aqueous H 2 SO 4 /CuSO 4 was investigated at two different initial concentrations of Ag + . The kinetics data of the process determined previously in the rotating cylinder were linked dire
