Corrosion inhibition of Floctafenine for zinc in 0.1 M HCl solution was studied using empirical and theoretical methods. Quantum studies have been utilized for studying the interaction between metal and inhibitor. Empirical methods like potentiodynamic polarization and electrochemical impedance spectroscopy were adopted to verify the inhibition efficiency of the inhibitor. Adsorption of the inhibitor follows the Langmuir isotherm. Thermodynamic values show the physical adsorption mechanism of the inhibitor. Activation and thermodynamic parameters explain the corrosion mechanism. The effect of temperature on the corrosion behavior of zinc in the given temperature range 303–333 K was studied and discussed.
