Abstract

The behavior of S235 metal, a general purpose metal construction material in Senegal, has been studied in perchloric acid solution in the presence of gum arabic from Senegal as a corrosion inhibitor. The protective power of this compound has been evaluated by electrochemical methods (stationary polarization curves and electrochemical impedance spectroscopy), at different inhibitor contents. We have considered testing gum arabic as an aqueous corrosion inhibitor. Electrochemical tests show that the values of the corrosion parameters vary with the content of gum arabic. An optimal inhibitory efficacy of approximately 88% is obtained for this substance, thus demonstrating the inhibitory nature.
