Using of Surfactant Nanostructures as “Green Compounds” in Corrosion Inhibition

A. Yousefi and S. Javadian
Abstract—The corrosion inhibition of some common surfactants and biosurfactant on mild steel has been investigated in hydrochloric acid at different concentrations of the inhibitor using mass loss, potentiodynamic polarization and electrochemical impedance spectroscopy measurements. The interest in these surfactants stems from their potential as ‘green compounds’ because of chemical and thermal stability, nonflammability, high ionic conductivity, and a wide electrochemical potential window, which makes them as good inhibitors. A significant decrease in the corrosion rate was observed in presence of the investigated inhibitor. The polarization curves showed that, the inhibitor behaves as mixed type but the cathodic effect is more pronounced. The surface tension at 298K was measured; the critical micelle concentration (CMC) and some surface active parameters were calculated. The inhibition efficiency (η %) of this surfactant has been studied by both chemical and electrochemical techniques at 25 ◦C. It was shown that an excess of cationic and anionic surfactant resulted in the formation of nanostructures. The observed corrosion data indicate that, the inhibition of mild steel corrosion is due to the adsorption of these molecules on the surface. The adsorption mechanism onto steel surface in acid medium in the absence and presence of surfactant was also discussed.
