Аннотация: Some novel green surfactants based on cottonseed oil were synthesized and tested as inhibitors for the corrosion of mild steel in CO2-saturated 1% NaCl solution by potentiodynamic polarization and linear polarization resistance corrosion rate measurements at 50°C. Their critical micelle concentrations at equilibrium in water at 25°C were also determined. Inhibition efficiency increased with increase in the concentration of the studied surfactants, reached the maximum (99.34%) at 100 ppm. The Tafel polarization results indicate that the inhibitors act as mixed inhibitors. The adsorption of the inhibitors on the steel surface obeys Langmuir isotherms. The thermodynamic parameters of adsorption revealed a strong interaction between the inhibitors and the corroding mild steel surface.
