orrosion control of mild steel in saline water solution by pomegranate leaf extract (PLE) is investigated at different inhibitor
concentration and temperature by using weight loss method. Inhibitor performance is enhanced with decrease of temperature
and increases with the raise of inhibitor concentration. Adsorption follows Langmuir adsorption isotherm with negative values of
adsorption heat, signifying a stable and spontaneous process of inhibition. Mathematical models were suggested to construct
a relationship between the corrosion rate data and independent variables with high correlation coefficients. Quantum chemical
parameters of inhibitor were calculated by using the AM1-SCF method to simulate the adsorption of the
PLE
molecules on steel
surface.
