Abstract
We investigated the cathodic and anodic processes in solutions of zinc sulfate in the presence of a surfactant and the background solution of sodium sulfate over a wide potential range. It was shown that anionic surfactants increase the anode current and the cation ones decrease. An explanation for the increase in the magnitude of the anode current in presence of anionic surfactants and reduction in the presence of cation-active surfactant was done. Experimental data and thermodynamic calculations has shown that the reason for the lack of influence of surfactants on the magnitude of the cathode current for the background electrolyte solution of sodium sulfate is probably associated with the processes of sulfate reduction.
