عنوان انگلیسی Corrosion Protection Performance of a Derivative of Quinoline [5-((3-Propyl-1H-Pyrrol-1-Yl) Methyl) Quinolin-8-Ol] PPMQ On Carbon Steel in Hydrochloric Acidic Solution 1 M
چکیده انگلیسی مقاله Organic inhibitors play a crucial role in the corrosion inhibition process. In this work, the performance of the derivative of quinoline PPMQ against corrosion of carbon steel in the acidic medium HCl 1 M was assessed using electrochemical methods. The findings of the experiments showed that the inhibitor had a strong inhibitory impact on the metal tested in the hydrochloric acid solution. The outcomes of the study displayed that the inhibition efficiency of the tested inhibitor enhanced with its concentrations and remained almost stable during immersion time while decreasing slightly with rising temperature. Electrochemical measurements of this study showed that the corrosion was greatly decreased by the organic inhibitor through a charge transfer mechanism with a high inhibition efficiency of 95.58% at an optimal concentration of 10-2 M at 293 K. While potentiodynamic polarization data reported that the inhibitor was a mixed-type inhibitor. PPMQ was inclined towards the Langmuir adsorption isotherm by spontaneous chemical-physical adsorption on the surface of carbon steel. Additionally, thermodynamic and activation data revealed that this action occurs through an endothermic process. Scanning electron microscopy findings showed that the inhibitor’s molecules form a protective layer, which confirms the electrochemical results.
