“…Table 4 provides activation parameters (E a , ΔH, ΔS) for the corrosion of mild steel in the presence and absence of prinivil, at various concentrations as shown in Figure 7 . For E a , the values increased from 18.42 kJ/mol (0 ppm) to 44.14 kJ/mol (500 ppm) ( Chowdhury et al, 2023 ; Katagiri et al, 2023 ; Zhang et al, 2023 ). In this context, an elevation in E a values with rising inhibitor dosage suggests that the inhibitor impedes the corrosion process by enhancing the energy barrier for corrosion initiation.…”

“…The weight loss assessment method is frequently employed to analyze the corrosion inhibition efficacy of inhibitors in various metals and alloys ( Thakur et al, 2019 ; 2020 ; Thakur et al, 2023 R. C. ; Nidhi et al, 2023 ; Pathania et al, 2023 ; Rana et al, 2023 ). By measuring the weight loss of a specimen as a consequence of the corrosion phenomena, this method offers important information about the C R and the efficacy of corrosion inhibitors ( Dong et al, 2023b ; Bijapur et al, 2023 ; Chowdhury et al, 2023 ). In our investigation, we conducted a weight loss evaluation following the immersion of samples in a 1M HCl media for 24 h as depicted in Supplementary Figure S1 .…”

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.

“…Furthermore, the study of corrosion inhibition with different plant ex-tracts in various mediums, i.e., acid solution, was also carried out by Liao et al [7], Hjouji et al [8], Shanmugapriya et al [9] and Ganash et al [10] In addition, Chowdury et al [11] and [12] concluded that the tulsi extract produced better inhibitory efficacy than the green tea extract in alkaline and acidic media. Fuchs-Godec [13] found that the inhibition efficiency reached more than 99% after a 1-hour immersion test and remained the same after five days on ferritic stainless steel with surface modification.…”

Wide application in the oil and gas industry made carbon steel suffer annual losses due to corrosion. The corrosion protection utilizes inhibitor have drawbacks expensive and harmful to the environment. Potato peel extract (solanum tuberosum L) and its main constituents, such as flavonoids, alkaloids, and tannins, have been investigated as a green corrosion inhibitor for low-carbon steel in a 3.5% NaCl solution. The inhibitor’s effectiveness and corrosion rate monitoring were measured using weight loss. Potentiodynamic polarization was used to investigate the type of corrosion inhibition and adsorption of plant extract on the surface. Fourier transform infrared spectroscopy (FTIR) was utilized to observe the presence of functional groups, natural compounds, and the type of bonding for adsorbed organic inhibitors on the surface. The results of the Tafel polarization analysis indicated that the potato peel extract acts as a mixed-type inhibitor. The inhibition efficiency increased with the concentration of the inhibitor extract. The optimal inhibition efficiency of 73.33% is was achieved with 6 ml of potato peel extract and 216 hours of immersion time. The inhibitive effect is due to the adsorption of inhibitor molecules on the steel surface, following the Langmuir adsorption isotherm.
