Abstract: 

Environmental sustainability is a serious problem, which needs to be overcome for practical application. Therefore, our goal is to develop the butanolic extract of the plant Hyppomarathrum Libanotis (EBHL), belonging to the Apiaceae family, as an API 5L Gr-B carbon metal deterioration inhibitor in 1M HCl solution. To test the efficacy of inhibition, the effects of solution concentration, immersion time, and temperature on the deterioration processes of API 5L Gr-B metal in 1 M HCl medium in the presence of an inhibitor were studied. The study included mass loss analysis, electrochemical impedance spectroscopy, and potentiodynamic polarization. The obtained tests showed that increasing the concentration improves the output of EBHL inhibition and achieves a value of 82 % at 700 ppm. The temperature rise contributed to a major drop in the production of inhibitions. Potentiodynamic polarization tests indicate the role of the extract as a dual-action inhibitor. In the Langmuir isotherm model, the main influence is on the anodic region, and as a result, a retention process occurs. Based on the above results, thermodynamic and activation parameters were established. Furthermore, deep structural and chemical analysis was also performed. X-ray photoelectron spectrometry and scanning electron microscopy were utilized for the study. The results indicate the formation of a protective coating on the carbon steel sheet.

Acid, inhibitor, steel, polarization, impedance, SEM, XPS <ParaStyle:Body>The aim of this work was to evaluate the Hippomarathrum libanotis plant as a corrosion inhibitor. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization are used to study the anticorrosion effect of the butanol extract of Hippomararthum libanotis. Polarization curves show that the extract is an excellent mixed inhibitor. Maximum inhibition efficiency of 80.23% was achieved with 700 mg/L of the inhibitor at 298 k. This investigation is complemented by morphological and surface chemistry studies using scanning electron microscopy (SEM) respectively. The results confirm the formation of a protective layer on the surface of the extract.
