Abstract

The inhibiting impact of Mentha piperita essential oil utilized as a natural corrosion preventer for Carbon steel in 1 M hydrochloric acid solution was examined utilizing electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) methods, UV-visible spectra and scanning electron microscopy (SEM)/(EDS). The results of these examinations demonstrated that Mentha piperita essential oil was a significant inhibitor. The inhibition efficacy (%IE) improved with rising essential oil of Mentha piperita leaves concentration and decreasing temperature. At 100 ppm, the extract showed exceptional inhibitory action, with an efficiency of 89.6% at 303 K. According to polarization curves, the Mentha piperita essential oil functions as a mixed inhibitor, it was clarified by the carbon steel surface absorbing Mentha piperita essential oil. The adsorption process follows the Langmuir isotherm. Studies on electrochemical impedance spectroscopy revealed a single capacitive loop, demonstrating the procedure of a charge transfer was responsible for controlling the corrosion reaction. The kinetic activation and adsorption process' thermodynamic characteristics were also estimated and explained.
