Abstract
In the present investigation a novel gemini surfactant namely N,NÕ-((oxalylbis(oxy))bis(ethane-2,1-diyl))bis(N,N-dimethyldodecan-1-aminium bromide) was synthesized, characterized, and tested as a corrosion inhibitor for carbon steel in 1Â M HCl solution. The corrosion inhibition efficiency was determined by using electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and weight loss methods. From the results, it was clear that the synthesized inhibitor is a good inhibitor for carbon steel in 1Â M HCl solution. The inhibition efficiency increases by increasing the concentration of the inhibitor. Thermodynamic and activation parameters were discussed. The synthesized inhibitor's adsorption was found to follow the Langmuir's adsorption isotherm.
