Abstract

The effect of carbonate ions for the type of polarization curves under anode polarization in carbonaceous solutions under different pH environments is investigated. The existence of two peaks on the curves of current-potential is shown. The substantiation of influence of carbonate ions on the anodic process is given. The mathematical model of dissolution of iron in carbonaceous solutions is offered .The mechanism of the description of polarizing curves of dissolution of iron in neutral and alkaline conditions is given.
