Abstract

Analysis of polarization curves for electrolytic dissolution of an iron (steel) electrode in citrate solutions of various pH values and concentrations of citrate anions showed that the given medium promotes the electrolytic dissolution by shifting the corrosion potential of iron to more negative values. However, the catalytic formation of an iron(II) hydroxo complex cation in the active dissolution region according to the scheme proposed by Heusler remains the rate-determining step of the dissolution mechanism.
