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.
