Various methods, including electrochemical impedance spectroscopy (EIS), weight loss, and potentiodynamic polarization (PP) were employed to synthesize, characterize, and asses the effectiveness of a new cationic gemini surfactant that serves as a carbon-steel (CS) corrosion inhibitor in 1 M HCl at 25-80°C. Based on the results, it was determined that the newly synthesized cationic gemini surfactant effectively inhibits CS in 1 M HCl. Raising the inhibitor's concentration and lowering the temperature may enhance the inhibition's efficiency. An investigation was conducted into the properties of activation and adsorption. The Langmuir adsorption isotherm has been discovered to be effective for inhibitor adsorption. The inhibitor is mixed-type inhibitor, according to potentiodynamic polarization tests.
