“…5a, and their related parameters are mentioned in Table 4. As showed in Nyquist plots, the impedance spectra appeared as a single capacitive loop at higher frequency range and its diameter increases with the increase in concentration, suggesting that the corrosion process is controlled by the charge transfer process and the adsorption of BEET on the steel surface formed a strength inhibitive film [31,42]. These loops are not perfect semicircles which may be attributed to the inhomogeneity and the roughness of the CS surface [43].…”

“…In our present study, the Langmuir adsorption isotherm, Eq. (6) [31], was found to be the most suitable mode to fit experimental data. At all temperatures, the values of regression coefficients (R 2 ) were almost close to unity (via Table 2), which confirm that the adsorption of BEET on the CS surface obeys Langmuir isotherm model.…”

The current investigation presents the corrosion activity of Elaeoselinum thapsioides (BEET) butanolic extract in 1 M HCl as a novel green source of corrosion inhibitor, and it's synergetic effect with another butanolic extract of Reutera lutea (BERL), whose belongs to the Apiaceae family. Weight loss measurements, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements have been done to study the inhibition efficiency. The obtained results showed that the inhibition efficiency of BEET alone increase with concentration and reached a value of 82% at 900 ppm. However, the maximum protection efficiency was more than 92% with the combination of BEET and BERL inhibitors. The rise of temperature caused a significantly decreased of inhibition efficiency. The potentiodynamic polarization results revealed that the extract functions as mixed-type inhibitor with predominance at anodic domain, and the adsorption process of the extract follows Langmuir isotherm. In addition, EIS shows that increasing the concentration of the inhibitor leads to an increase of the charge transfer resistance and reducing the double layer capacitance. The synergistic factor (S) was used to investigate the synergistic behavior of the selected inhibitors.

The corrosion inhibition properties of a synthesized hydrazone derivative namely, 1-(4-isopropyl phenyl)-2-(2,4-dinitrophenyl) (HYD (iso)) on API 5L-X60 carbon steel (CS) in 1.0 M HCl solution were evaluated by chemical, electrochemical, X-ray photoelectron spectroscopy (XPS) and theoretical studies. The obtained results revealed that the tested compound acted as a good corrosion inhibitor with inhibition Journal Pre-proof J o u r n a l P r e-p r o o f 2 efficiency of 96.32% at a concentration of 5×10-3 M. The polarization technique indicated that the HYD (iso) belonged to mixed-type inhibitors, preventing simultaneously anodic and cathodic reactions. The binding between the HYD (iso)'s molecule and CS surface follows a Langmuir adsorption type model and its inhibition mechanism is assisted by physical and chemical interactions. Scanning electron microscope (SEM) and contact angle analyses were performed to examine the surface morphology of inhibited and uninhibited samples. Additionally, theoretical studies using Density Functional Theory (DFT) and molecular dynamics (MD) simulation were performed to explore the most reactive sites of the hydrazone molecule and its adsorption mechanism.
