Abstract
Artemisia herba-alba essential oil extract was investigated as green inhibitor for aluminum corrosion in 1 M HCl solution. The chemical analysis obtained by gas chromatography and gas chromatography–mass spectrometry, revealed 68 components. The inhibition efficiency was determined by weight loss measurements, potentiodynamic polarization, electrochemical impedance spectroscopy and scanning electron microscope. The results revealed an increase of inhibition efficiency by maximum 92% trough increasing the oil concentration to 3 g/L at 333 K. The oil compounds adsorb by physisorption, follow Langmuir adsorption isotherm and act as mixed type inhibitors. The EIS results confirmed the adsorption mechanism process and the SEM observations.
