Abstract
ABSTRACT Oil of Melia azedarach seeds (MA-oil) was extracted and modified in the form of amido poly amine surfactant (MA-amido surfactant). The surface active properties of the new MA-amido surfactant were analyzed. Corrosion inhibition of C-steel in 2.0 M HCl by MA-amido surfactant was investigated using weight loss (WL), potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). The results indicated that the corrosion of C-steel was obviously reduced. PDP curves showed that the MA-amido surfactant behaves as a mixed-type inhibitor. The adsorption process at the C-steel surface obeys Langmuir adsorption isotherm model. The activation and thermodynamic parameters of the adsorption were evaluated and discussed. The protective film at the metal surface was characterized by a scanning electron microscope (SEM).
