Sažetak
The inhibition effect of olive leaf extract on corrosion of carbon steel in brine solutions saturated with CO2 was investigated at 25°C and 65°C by means of Tafel polarization, weight loss measurements and Fourier transform infrared spectroscopy. The experimental results reveal that the olive leaf extract has a good inhibition effect on the carbon steel in CO2- saturated brine solution at both temperatures. Tafel polarization investigations revealed that olive leaf extract acted as a mixed inhibitor showing anodic and cathodic behavior. The adsorption of olive leaf extract on carbon steel surface obeyed the Langmuir adsorption isotherm. The adsorption thermodynamic parameters indicated the physisorption of olive leaf extract on carbon steel surface was a spontaneous and exothermic process with an increase in entropy. Fourier transform infrared spectroscopy spectra showed types of bonding for olive leaf extract on the carbon steel surface.
