“…Transitory Electrochemical tests of interface of steel with HCl acid in the absence and presence of inhibitors imid1 and imid2 in the concentration ranging from 10 -3 M to 10 -5 M, after the addition of Imid in the concentration ranging from 10 -3 M to 10 -5 M, the experimental device to perform these electrochemical measurements is a potentiostat. The PGZ 301 radiometer in the frequency range of 100KHz to 10 mHz with an amplitude of about 10 mV, At this time, the Determining the EIS from the Nyquist and Bode traces allows us to perform the several processes related to the efficience of steel protection against acid attack using the following equations (5) [27,28].…”

The present study was devoted to the investigation of the effect of NO2 and OH group in the structure of two imidazopyridine, namely: (E)-N-(7-methyl-2-phenylimidazo[1,2-a]pyridin-3-yl)-1-(4-nitrophenyl)methanimine (Imid1) and (E)-4-(((7-methyl-2-phenylimidazo[1,2-a]pyridin-3-yl)imino)methyl)phenol (Imid2) on the corrosion inhibition efficiency of steel in acidic medium, to remediate mild steel in hydrochloric acid. The evaluation of this activity was revealed using several experimental techniques such as: weight loss measurements (WL), potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS), UV-visible spectroscopy study, surface characterization by SEM, as well as the impact of temperature and concentration on the inhibition efficiency for two inhibitors. The results obtained from these techniques show that the inhibition efficiency is reduced by the effect of the nitro electron withdrawing group (NO2) in the Imid1 molecule, but increased by the presence of the donor group (-OH) in the Imid2 molecule. The comparison of the results obtained by UV-visible spectroscopy of the inhibited and uninhibited electrolyte provided evidence for the formation of an Fe-ligand complex of two imidazopyridine molecules in 1M HCl. Surface morphological studies by SEM revealed a uniform surface in the presence of the imid1 − 2 in contrast a destroyed surface in the absence of the inhibitors. Finally the results of DFT and MDS simulations are in good order with the experimental data and showed that the obtained order of the inhibition efficiency is always respected (Imid2 > Imid1).

The present article investigates the corrosion inhibition properties of N‐protected amino acids in .5 M H2SO4 solution on mild steel by gravimetric studies, potentiodynamic polarization method, and impedance spectroscopic techniques at different temperatures. This article evaluates synthetic methodology, characterization, and theoretical studies of N‐protected amino acid inhibitors with their anticorrosive property. Theoretical studies were conducted in the gaseous phase through a 6‐31 G (d, p) basis set from the B3LYP method. Potentiodynamic polarization studies revealed that both N‐protected amino acids behave as mixed‐type inhibitors. Impedance spectroscopic data confirmed the adsorption of the inhibitor on the metallic surface. Adsorption isotherm was employed to calculate the Gibbs free energy change. Langmuir adsorption isotherm is more acceptable for adsorption phenomena exhibited by the inhibitors. Thermodynamics and kinetic parameters of this adsorption phenomenon indicate that L2H was more efficient (94.13 ± .01% at .004 mol/L) than L1H (93.62 ± .02% at .004 mol/L) at 303 K. Surface morphology analysis of uninhibited and inhibited mild steel samples confirms that N‐protected amino acid inhibitors efficiently inhibit corrosion.
