عنوان انگلیسی The Inhibiting Effect of Aqueous Extracts of Artemisia Absinthium L. (Wormwood) on the Corrosion of Mild Steel in HCl 1 M
چکیده انگلیسی مقاله Using the decoction extraction method, we obtained twice crude aqueous extracts of Artemisia absinthium or (wormwood) that was made to start a comparative study, between the first extract which corresponds to the leaves of our plant (AQL) and the second which belongs to the stems (AQS). The inhibitory activity of the twice extracts of Artemisia absinthium was studied by weight loss, potentiodynamic polarization and electrochemistry impedance spectroscopy. The morphology of the mild steel surface was examined by SEM.The inhibitory efficiency increased with the increase of the concentration, we reach an efficiency of 85% for AQL and 82% for AQS at 303 K for a concentration of 0.2 g/ L. Two Artemisia absinthium extracts used to prevent corrosion in mild steel adhere to the Langmuir adsorption isotherm during adsorption. The majority compound is 3,4-dihydroxybenzoic acid in the case of extracts with percentages of 42.4% for AQL and 42.2% for AQS. The DFT results of the majority compounds allowed us to have an idea on the power of adsorption of these last ones on the surface of the metal, indeed there can be a combined effect of the various molecules constituting the extracts on the corrosion inhibition.
