عنوان انگلیسی Anti-Corrosion Performance of Ruta Graveolens Essential Oil as A Green Inhibitor for Mild Steel in 1 M HCl: Evaluations of Electrochemical, DFT And Monte Carlo
چکیده انگلیسی مقاله Environmental issues have received considerable attention in recent years, and the use of green corrosion inhibitors has become the main topic of most researchers. The current study was focused on evaluating the essential oil from aerial parts of the Ruta Graveolens L. (RG-(EO)) has been used as an eco-friendly corrosion inhibitor on Mild Steel (MS) at 1 M HCl solution. The characterization method (i.e., gas chromatography-mass spectrometry (GC/MS)) identified 21 constituents representing 95.3% of the total amount and undecan-2-one (U2ONE) has been identified as the main constituent of RG-(EO). The inhibiting effect of RG-(EO) on the corrosion of MS in 1 M HCl solution was tested by the measurements of Weight loss (WL), potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS) as well as quantum chemical calculation methods. The PDP test findings showed that the effectiveness of MS inhibition increased with the addition of the RG-(EO), reaching almost 94.80% at 2.00 g/L. The thermodynamic analysis showed that the inhibition efficiency increases slightly with an increase in the temperature of the medium (308-343 K). Moreover, the thermodynamic kinetic parameters showed that the adsorption of RG-(EO) on MS surface sites is subject to the Langmuir adsorption isotherm. Finally, the theoretical studies based on quantum chemical analysis (i.e. density functional theory (DFT)) and Monte Carlo (MC) simulation were also performed for understanding the adsorption mechanism of U2ONE onto Fe-surface.
