عنوان انگلیسی Revolutionizing Corrosion Defense: Unlocking the Power of Expired BCAA
چکیده انگلیسی مقاله Corrosion of mild steel in acidic environments presents a significant challenge across diverse industries. This pioneering research explores the novel potential of expired BCAA (Leucine, Isoleucine, and Valine) as a dynamic corrosion inhibitor for mild steel immersed in HCl solution. Through meticulous weight loss techniques, we quantified the corrosion rates of mild steel, both with and without the intervention of BCAA. Complementing our experimental approach, Density Functional Theory (DFT) calculations illuminated the intricate molecular interactions between BCAA and the metal surface. Furthermore, a comprehensive study of the adsorption isotherm unraveled the adsorption behavior of BCAA molecules on the mild steel surface. Remarkably, the inhibition efficiency of BCAA soared to an impressive 92.2 % at a concentration of 500 mM, a temperature of 303 K, and an immersion time of 5 hours. However, with the temperature increase to 333 K, a notable reduction in inhibition efficiency was observed. Intriguingly, the adsorption isotherm analysis showcased BCAA's adherence to the Langmuir adsorption isotherm, revealing additional insights into its inhibitory prowess. These groundbreaking findings highlight the untapped potential of expired BCAA as a corrosion inhibitor, offering valuable insights into its inhibition efficiency, temperature dependence, and adsorption behavior.
