عنوان انگلیسی Evaluation of the Inhibiting Power of Essential Oil Extracted from Cloves (Syzygium Aromaticum) on Corrosion of Steel C24 In Medium HCl 1M
چکیده انگلیسی مقاله The objective of this research is to enhance the value of the clove tree (Syzygium aromaticum), an aromatic and medicinal plant found in Senegal. The focus is on assessing the inhibitory effect of the essential oil extracted from clove on C24 carbon steel in a 1M HCl medium. In the initial phase of the study, essential oil was extracted from the cloves through hydrodistillation utilizing a Clevenger-type extractor. These extractions yielded an average extraction rate of 11.7%, a notably commendable figure when compared to various data reported in existing literature. Subsequently, the extracted essential oil underwent characterization employing standard chromatographic techniques (GC/IR, GC/MS). This allowed for identification of the chemical compounds constituting the essential oil, with major compounds identified as Eugenol (64.97%), Caryophyllene (24.15%), and Acetyleneugenol (6.19%). The research delved into investigating the inhibitory impact of clove essential oil on C24 steel in a 1M HCl medium using electrochemical techniques. The outcomes of this investigation indicated an optimal efficacy of 88.52% for an essential oil concentration of 4g/L at 290K. Furthermore, the study assessed the influence of temperature on the inhibitory properties of the essential oil across a temperature spectrum of 290 to 338 K. Within this temperature range, a marginal reduction in efficiency was noted with increasing temperature, ultimately 79.92% at 328 K. Subsequently, thermodynamic parameters were computed. The graphical representation of the distinct isotherms demonstrated that the adsorption of the essential oil adhered to the Langmuir isotherm. The results underscored a blended adsorption characteristic of this essential oil.
