Carbon Steel, Corrosion inhibition, Lagenaria Siceraria Leaves, Adsorption isotherms.

Adsorption behavior of Carbon steel in 1.0N HCl solution in the presence of Lagenaria Siceraria Leaves (LSL) extract was studied by mass loss measurements with various periods of contact and temperature. Inhibition efficiency increased with increase of inhibitor concentration. The inhibitive effect of the Lagenaria Siceraria leaves could be attributed to the presence of some active compound which is adsorbed on the surface of the Carbon steel. The LSL was found to conform by various adsorption isotherms viz., Langmuir adsorption, Temkin adsorption, Florry-Huggins adsorption, Frumkin adsorption, Freundlich adsorption and El-Awady adsorption isotherm at different concentration and temperature investigated and inhibitor obeyed Langmuir adsorption isotherm. Thermodynamic parameters also revealed that the adsorption process is spontaneous.
