Abstract
Inhibition of corrosion of carbon steel in phosphoric acid solution by use of lcysteine methyl ester hydrochloride has been investigated by measurement of weight loss and use of electrochemical methods The efficiency of inhibition was increased by increasing the concentration of the inhibitor and reduced by increasing the temperature Polarization studies revealed that this compound behaves as mixedtype inhibitor Electrochemical impedance spectroscopy showed that dissolution of the steel occurs as a result of chargetransfer Adsorption of the inhibitor obeyed the Langmuir adsorption isotherm Kinetic and thermodynamic data were calculated and are discussed
