摘要：2-oxo-1,2-dihydroquinoline-4-carboxylic acid (Q=O) was synthesized and its inhibiting action on the corrosion of mild steel in 1 M hydrochloric acid and 0.5 M sulfuric acid was examined by different corrosion methods, such as weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The experimental results suggest that this compound is an efficient corrosion inhibitor and the inhibition efficiency increases with the increase in inhibitor concentration. Adsorption of this compound on mild steel surface obeys Langmuir isotherm. Correlation between quantum chemical calculations and inhibition efficiency of the investigated compound is discussed using the Density Functional Theory method (DFT).
