Abstract
A model of electrochemical acid corrosion of iron in the presence of i nhibitors is presented. The model allows for a theory of the effect of a surfactant on the kinetics of electrode processes. Computer-aided c alculations show that the model agrees with experiments better than a model based only on the retarding action of inhibitors. Variations in b(a), b(c), dlogj(a)/dpH, and dlogj(c)/dpH parameters in the presence of inhibitors are due to the dependence of degree of coverage on the e lectrode potential and pH of the solution.
