Abstract

The effect of the concentration of sodium hydroxide with and without potassium oleate on electrochemical behavior of lead has been investigated using cyclic voltammetry. It has been shown that the number of anode and cathode peaks on the curve depends on the potential scan rate and the concentration of alkali. Anode peaks are related to the formation of lead compounds (PbO and PbO2), the presence of which has been confirmed by X-ray phase analysis. It has been determined that the dissolution of lead in sodiumhydroxide solution with and without potassium oleate proceeds under diffusion-kinetic control. Potassium oleate facilitates lead passivation in the solutions with lower concentration of alkali decreasing the potential and current of active–passive transition and does not affect or restricts it in more concentrated solutions.
