Effect of 2 – thiocytosine on the parameters of double R-AgLAFe/ chlorate(VII) interface layer in the presence of different surfactants has been studied. There were determined the adsorption parameters such as: differential capacity of the double layer (Cd) at the R-AgLAFe/ basic electrolyte interface; potential of zero charge (Ez) and surface tension at the potential of zero charge (γz). The predominance of 2–thiocytosine in formation of adsorption equilibria of 2–thiocytosine–SDS and 2– thiocytosine–CTAB mixtures as well as the competitive adsorption between molecules 2–thiocytosine-surfactant or mixed micelles was proved. The changes pointing out to different arrangement of SDS or CTAB molecules on the electrode surface also in the presence of 2–thiocytosine were observed.
