The severe consequences of corrosion process cause global issues most especially in petroleum refineries. This research investigates performance evaluation and optimization of bryophyllum pinnatum leaves extract for mild steel corrosion inhibition. The extract was subjected to phytochemical analysis to determine the inclusion of any bioactive component. Box Behnken design was used to optimize process variables which include Temperature (30°C-60°C), Immersion time (3–12 days), and amount of extract (0.2–0.8 g/l). Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM) and Energy Dispersive Spectroscopy (EDS) were used for characterization. Phytochemical analysis revealed the presence of flavonoids, tannins, saponins, alkaloids, terpenoids, and steroids. It was established from experimental results that Temperature of 30°C, Immersion time of 3 days, Inhibition concentration of 0.8g/l gave the best process, while the optimal process variables gave: Immersion time: 6.3 days, Inhibition concentration: 0.63g/l days; Temperature: 58.6°C respectively. The results of SEM, EDS and FTIR revealed that mild steel via validated optimal process level had more protective film and was formed through adsorption. Hence, Bryophyllum pinnatum extract has been established as an effective corrosion inhibitor.

“…Consequently, the concurrent assessment of various parameters on WL, CR, and IE can be expedited through these design methods, facilitating a comprehensive understanding of LAE's performance in corrosion control.A valuable and practical approach in this context is the utilization of the Response Surface Method (RSM) [33][34][35] . RSM comprises a collection of statistical and mathematical techniques highly useful for simulating and assessing problems where the response variable is influenced by numerous independent parameters, with the ultimate goal of optimizing these responses [36]. A key advantage of RSM lies in its ability to significantly reduce the number of required tests when evaluating multiple variables and their interrelationships.…”

In this study, the CCD response surface methodology was used to model and optimise the performance of Lasienthera africanum leaves extract (LALE) as a corrosion inhibitor on mild steel. The experimental parameters were assessed at different immersion time and inhibitor concentration to determine the optimum conditions for corrosion mitigation. Using experimental results of the corrosion characteristics such as the weight loss, corrosion rate, and inhibition efficiency of LALE, new models were developed, the significance of which was tested using variance analysis. The developed RSM models of WL, CR, and IE were accurate and reliable, and their P-values were 0.0001, which is less than 0.05. Likewise, the R2-statistics (R2, adjusted-R2, and predicted-R2), adequate precision, and diagnostic plots were also used as a means to ascertain the degree of accuracy and adequacy of the WL, CR, and IE models. In addition, optimization of the corrosion inhibition process for LALE revealed that the optimum conditions for maximum IE, minimum WL, and CR were achieved at a concentration of 93.93 ppm and an immersion time of 228 hrs. Under these settings, the inhibition efficiency, weight loss, and corrosion rate were 93.85%, 0.294g and 3.267 mm/y, respectively. Therefore, the models are considered ideal for prediction with a confidence level of 95%, and the optimal combination is suitable for the corrosion inhibition process design. Hence these models can be recommended for applications such as oil well acidizing and pickling pipelines.

This study explores Daucus crinitus extracts (DCE) and zinc oxide nanoparticles (ZnO-NPs) synthesized using the extracts as corrosion inhibitors for carbon steel (CS) in HCl medium. The synthesized ZnO-NPs were characterized via UV-vis spectroscopy, exhibiting a peak at approximately 375 nm. The study employed weight loss (WL) and electrochemical measurements, alongside spectrophotometric evaluation of corrosion products. Surface morphology was assessed via scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS). Thermodynamic analysis revealed the physical adsorption of DCE on CS according to the Freundlich adsorption isotherm. Potentiodynamic polarization (PP) measurements indicated DCE as a mixed-type corrosion inhibitor. Electrochemical impedance spectroscopy (EIS) exhibited increased charge transfer resistance and reduced double-layer capacitance with inhibitory addition. The most effective inhibition was observed with butanol extract (BE) and improved more with its corresponding nanoparticles (BENPs), exhibiting inhibitory efficiencies of 80.20% and 91.20%, respectively, at 298 K with a concentration of 800 ppm. The evaluation of corrosion products using colorimetry revealed that the concentration of polyphenols decreased after the inhibitory process. Furthermore, the intensity of ferrous ions (Fe2+) decreased as the inhibitory concentration increased. In addition, SEM-EDS analysis confirmed the presence of ZnO-NPs, which enhanced the surface morphology and established a protective layer formed by the adsorbed inhibitors. The SEM-EDS analysis confirmed the presence of ZnO-NPs, the enhancement of surface morphology, and the establishment of a protective layer formed by the adsorbed inhibitors.
