Abstract :

The electrochemical behavior of carbon steel in simulated fuel grade ethanol (SFGE) and the effect of water and chloride ion have been studied by using cyclic voltammetry and potentio-dynamic polarization techniques and complemented by scan electron microscope (SEM) investigations. The presence of water and chloride ion in SFGE strongly influences the electrochemical behavior of carbon steel. The increase in water and chloride ion concentrations induces pitting and general corrosion. Polarization curves indicate that PEG-40 HCO has good inhibition efficiency and behaves as mixed inhibitor. The adsorption of PEG-40 HCO obeys Langmuir adsorption isotherm.
