摘要：

This work aims at studying the influence of Methanolic Extract of Artemisia (MEA) on copper corrosion inhibition in 0.5 M HNO3. The study introduces a novel approach to copper corrosion inhibition in nitric acid using MEA, offering an eco-friendly, biodegradable and sustainable attributes. This aligns with modern environmental and societal concerns. In this context, experimental methods were exploited to investigate the inhibitive action of MEA. According to Potentiodynamic polarization (PDP), Electrochemical Impedance Spectroscopy (EIS) and Weight Loss measurements (WL), the increment of the inhibition efficacy (IE %) depends on the increase of MEA concentration. A maximum of 94 % was obtained in the presence of 550 ppm (MEA), which showed a decrement as temperature increased. The action of MEA was attributed to its adsorption on copper surface following Langmuir isotherm. SEM analysis showed a significant improvement in Cu surface morphology, which had a hydrophobic character after MEA addition as indicated by contact angle (CA) measurements. UV-Vis and solution analysis techniques highlighted the development of a protective layer that mitigated copper dissolution and hindered the access of aggressive ions to copper.
