The inhibition of the corrosion of carbon steel in hydrochloric acid solution by Lipid Oil Melia (LOM) has been studied using weight loss, electrochemical impedance spectroscopy and potentiodynamic polarization techniques. The inhibition efficiency of this inhibitor increases with increase in concentrations. The maximum inhibition efficiency of LOM was achieved at 3 g/L concentration. The inhibition efficiency of the inhibitor decreases on increasing the temperature from 298 to 328K. The Tafel polarization studies indicate that this compound acts as a mixed type inhibitor. As the inhibitor concentration increased, the charge transfer resistance of carbon steel increased and double layer capacitance decreased. The adsorption of LOM on the surface on carbon steel has been found to obey the Langmuir adsorption isotherm, and the values of free energy of adsorption are calculated. Kinetic parameters (activation energy, pre-exponential factor, enthalpy of activation and entropy of activation) were calculated and discussed.
