“…An inhibitor’s inhibition efficiency is immensely dependent on the inhibitor dosage and immersion time [ 72 ]. Hence, RSM/CCD optimization was performed to determine an optimum value of dosage and immersion time for maximum efficacy of EFB-H. Table 6 demonstrates the preliminary study result.…”

This study aims to develop a controlled release oil palm empty fruit bunch hemicellulose (EFB-H) inhibitor tablet for mild steel in 1 M HCl. As plant extracts tend to deteriorate at longer immersion time, limiting its industrial applicability, we attempted to lengthen the inhibition time by forming a controlled release inhibitor tablet. Electrochemical methods (potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS)) were employed to investigate the efficiency and mechanism of the inhibition. An optimum dosage and immersion time was determined via Response Surface Methodology (RSM). EFB-H tablet was formulated using D-optimal mixture design, and its anticorrosion action at extended immersion time was compared with EFB-H powder. PDP measurement revealed that EFB-H is a mixed type inhibitor. RSM optimization unveiled that the optimum point for a maximum inhibition efficiency (87.11%) was at 0.33 g of EFB-H and 120 h of immersion time. Tablet T3 with EFB-H to gum Arabic to hydroxypropyl methylcellulose ratio of 66:0:34 portrayed the best tensile strength (0.243 MPa), disintegration time (152 min) and dissolution behavior. EFB-H tablet exhibited a longer-lasting inhibition effect than powder, which was 360 h as compared to 120 h for powder. Overall, EFB-H tablet has been successfully developed, and its enhanced effective inhibition time has been experimentally proven.

The inhibitive effect of mebendazole (MBZ) on the corrosion of low-carbon steel in H2SO4 was investigated by gravimetric and electrochemical techniques as well as examination of specimens in the scanning electron microscope with attached energy dispersive X-ray spectrometer (EDS). From gravimetric analysis, the highest inhibition efficiency of about 96.6% was obtained for 1.0 g of inhibitor in H2SO4 solution at 24 h, while with longer exposure times of between 72 to 120 h, the efficiencies averaged between 92 and 95%. Tafel extrapolations from the polarization curves showed that 1.0 g MBZ gave a maximum inhibition efficiency of approximately 99% for the investigation conducted at 30°C, whereas 1.5 g of MBZ gave a maximum inhibition efficiency of about 85% at 60°C. Inhibition efficiency increased with increasing concentrations of MBZ and decreased at elevated temperatures. The inhibitive action was attributed to physical adsorption of MBZ species on the mild steel surface which followed the Langmuir adsorption isotherm. MBZ performed as a mixed-type inhibitor on mild steel in dilute H2SO4.

“…Any point on the 3D surface plot can be selected to show details about the response prediction at that levels of the factors. The relative interaction of the factors (reinforcement particle sizes and volume fraction) and their magnitude of influence on the properties of the developed composites could be observed by the nature of 3D surface plots [41]. The peak level and design points above the predicted values for each property analyzed lies in the red colour.…”

“…Response surface methodology (RSM), has been successfully utilized among other experimental design and optimization techniques for the predictive modelling and process factor optimization of composite materials [37][38][39]. RSM is a statistical and experimental design tool in which a specified dependent variable or materials property responds to experimental variations in one or more independent process factors [40][41][42][43]. There is little or no researches on the use of hardwood charcoal to improve the tribological and other mechanical properties of wood charcoal-polymer composites [38,44].…”
