“…Upon examining the cathodic plots depicted in Figure 5, it is evident that the addition of M. prolifera fruit extract led to a substantial reduction in current density within the 1.0 M HCl solution. This observation suggests that the M. prolifera fruit extract acted as a cathodic inhibitor in the 1.0 M HCl solution [13]. The findings obtained from both experimental methods complemented each other, leading to the conclusion that the adsorption of M. prolifera fruit extract on the metal surface is an inevitable phenomenon.…”

In this study, it was aimed to examine the adsorption and corrosion behaviours of the aqueous extract of Mammillaria prolifera, a cactus fruit, in 1.0 M HCl solution using experimental methods such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Mammillaria prolifera is a cactus species from the Cactaceae family, commonly known as Texas nipple cactus. Experiments were realized for aqueous extracts of four different Mammillaria prolifera fruits. The results indicate that the aqueous extract solution of cactus fruit has outstanding anti-corrosive performance of over 90% at the optimum concentration of 0.120% (w/v). In addition to electrochemical experiments, FE-SEM surface images were taken as another indicator of high inhibition. The results showed that the mild steel surface immersed in the inhibited electrolyte solution at 298 K after one-hour exposure did not contain cracks, pits or deformations compared to the inhibitor-free surface. As a result, experimental measurements and FE-SEMsurface images support each other.

“…To assure a stable condition prior to commencing the evaluation, the working electrode was submerged in 1 M HCl solution both in the exclusion and inclusion of Prinivil for around an hour at the Open Circuit Potential (OCP). Subsequently, polarization curves were scanned at a rate of 1 mV/s by varying potentials around the recorded OCP after a 1-h immersion period ( Akkoç et al, 2023 ; Shi et al, 2023 ).…”

The deterioration of mild steel in an acidic environment poses a significant challenge in various industries. The emergence of effective corrosion inhibitors has drawn attention to studies aimed at reducing the harmful consequences of corrosion. In this study, the corrosion inhibition efficiency of Prinivil in a 1M HCl solution through various electrochemical and gravimetric techniques has been investigated for the first time. The results demonstrated that the inhibition efficiency of Prinivil expanded from 61.37% at 50 ppm to 97.35% at 500 ppm concentration at 298 K. With a regression coefficient (R2) of 0.987, Kads value of 0.935 and Ea value of 43.024 kJ/mol at 500 ppm concentration of inhibitor, a strong affinity of Prinivil for adsorption onto the metal surface has been significantly found. Scanning electron microscopy (SEM) and contact angle measurement analyses further support the inhibitory behavior of Prinivil, demonstrating the production of a defensive layer on the surface of mild steel. Additionally, molecular dynamics (MD) and Monte Carlo simulations were employed to investigate the stability and interactions between Prinivil and the metallic surface (Fe (1 1 0)) at the atomic level. The computed results reveal strong adsorption of Prinivil upon the steel surface, confirming its viability as a corrosion inhibitor.
