عنوان انگلیسی Exploring the Corrosion Inhibition Potential of 2-(2-Aminopropyl)thiazole for MS in Acidic Environment: Methodological and Theoretical investigation
چکیده انگلیسی مقاله Mild steel (MS) corrosion in acidic environments presents significant challenges due to the limitations of conventional inhibitors, including concerns related to toxicity and environmental impact. This research explores the potential of 2-(2-Aminopropyl)thiazole (APT) as an inhibitor for corrosion of MS in 1 M HCl environment through methodological and DFT combination study. The inhibitory performance of APT reached an impressive efficiency of 88.2 % under optimized conditions (0.5 mM inhibitor concentration, 303 K), demonstrating its promise as an environmentally friendly alternative. Analysis based on Langmuir adsorption isotherm indicated strong and specific interactions between APT molecules and the steel surface, suggesting the formation of a protective film over time. The correlation between inhibition efficiency, immersion time, and temperature revealed a gradual enhancement of the protective effect, with temperature positively influencing the inhibitor's effectiveness, indicative of a thermally activated adsorption process. Calculations of Density Functional Theory (DFT) supported experimental findings and provide insights into molecular interaction at the interface. Just in these case, the calculated theory of electron transfer suggested that the interaction between APT and the atoms of iron was more favorable what shifted the inhibition process in a good direction. This work not only provide important information about the role of corrosion inhibiting but also relies on a reliable methodology that can be genralised to the analysis of eco-friendly corrosive preventing substances. Moreover, the research results provide a basis for the future development of APT for industrial application, which will deal with the real-world problems in the world.
