“…15 Depending on the location and the part of the plant employed, both the yield of these natural substances and the potential to inhibit corrosion vary greatly. 16 Because of their biodegradability, their ecological character and their low cost, [17][18][19] several studies have been devoted to the green inhibition of the corrosion of metals by essential oils. The study of Belarbi et al 14 on the use of L. Stoechas oil as a corrosion inhibitor for steel in 1 M HCl medium indicated that the oil gave a good inhibition efficiency of 61.97% at 2 g/L oil at 30°C, Belarbi et al 4 also conducted a study on the influence of Ammodaucus Lecotrichus on copper corrosion in 2 M HCl solution, the results revealed an efficiency of 70% for a concentration of 3000 ppm at 25 °C.…”

The present study was designed to predict and analyze the effect of the essential oil of Ammoides verticillata (A.E.O) originating from the city of Souahlia (Tlemcen), which is located in northwest Algeria and its major compound on the inhibition of copper corrosion in 1 M HNO3. Gas chromatography coupled with mass spectrometry (GC-MS) revealed that carvacrol constitutes 67.89% of the essential oil. The study investigated the effect of concentration and temperature on copper corrosion and inhibitory efficiency using the gravimetric method. The findings indicate that A.E.O and carvacrol independently exhibit good inhibition properties on copper in 1 M HNO3, with the highest inhibitory efficiency at 1.5 g/L for A.E.O and 0.1 g/L for carvacrol, respectively. The adsorption of A.E.O and carvacrol on copper follows the Langmuir and Frumkin isotherm, respectively. The study also found competitive adsorption between iodide ions and A.E.O, as shown by the synergy parameter. Finally, Raman spectroscopy was used to analyze the immersed copper surface and mapping was used to characterize the surface layers in the different corrosive media used, which allowed us to develop a precise mapping of the corroded parts with the inhibited parts. This method will allow us to really see the inhibition effect of our materials.
