“…Waste citrus limonum peels was tried as corrosion inhibitor against A36 mild steel in 0.5 M H 2 SO 4 and to establish the appropriate adsorption isotherms for the corrosion inhibition process Langmuir, Temkin and Freundlich adsorption isotherm were established. From the regression coefficient, it is clear that Langmuir adsorption and Freundlich adsorption model best describes the adsorption mechanism (19).…”

Owing to the high economic and environmental concerns, nowadays scientists have taken much attention to mitigate corrosion. The effectiveness of Garcinia gummi-gutta leaf extract (GGLE) at inhibiting corrosion on mild steel in 1 M HCl was examined in the current study using a weight loss strategy. The GGLE concentration was changed from 100 to 6000 ppm, and the results show that expanding the inhibitor concentration increased the efficacy of corrosion inhibition. At 6000 ppm concentration and 30°C, the maximum inhibitory efficiency was 82.2%; this efficiency decreases as temperature increases. The mechanism of sorption was deliberated by means of different adsorption isotherm and Langmuir adsorption isotherm model holds good for elucidating the adsorption mechanism. The thermodynamic and kinetic parameters were estimated to depict the corrosion process. X-ray photoelectron spectroscopy (XPS) was also used to confirm the development of a coating of inhibitor fragments that protect the metal surface.

“…The SEM image shows that the C-steel surface with hydrazone inhibition appears undisturbed. 38,39 The C-steel surface becomes less harmed than the blank by adding 4.95 × 10 −3 mol/L HTZS (Figure 10C), and some larger pores and cracks are created on the surface. The C-steel surface (Figure 10D) becomes extremely smooth and corrosion-free as the concentration of HTZS (99.0 × 10 −3 mol/L) increases.…”

This work focuses on developing corrosion control and protecting the environment by creating affordable, sustainable, environmentally friendly, and efficient corrosion resistance chemicals. That is, through synthesized three hydrazone Schiff bases E-2-(1-hydrazonoethyl)thiazole (HTZ), 2-((E)-(((Z)-1-(thiazol-2-yl)ethylidene)hydrazono)methyl)phenol (HTZS), and 2-((E)-(((Z)-1-(pyridin-2-yl)ethylidene)hydrazono)methyl)phenol (HPYS) and corrosion inhibitors for C-steel in 8 M H 3 PO 4 solution that were studied. The chemicals were analyzed by using 1 H NMR and 13 C NMR spectroscopy to learn more about them.Predominantly, the hydrazone-based Schiff bases have been considered powerful inhibitors due to their ability to be adsorbed with very low concentrations through their reactive sites (N, O, and S). Maximum surface (θ max ) coverage and inhibition efficiency of 83.33% were sufficiently found at 99.00 × 10 −3 mol/L concentration of HTZS at 293 K. Galvanostatic experiments demonstrated that raising the concentration of hydrazones improved mass transfer resistance. To study microstructure, scanning, reflectance, and energy-dispersive X-rays were used. Roughness and qualitative adhesion of the adsorbed layer were estimated by an atomic force microscope. After adding 99.00 × 10 −3 mol/L of HTZS, the degree of surface brightness and reflectance increases to 137.20, relative to the corroded electrolyte-free solution 27.70. The roughness (Ra) decreased from 0.468 to 0.088 μm by adding HTZS. A surface morphology study confirmed that adding hydrazones to the C-steel dissolution bath greatly improves the surface's look and texture quality. The atomic absorption spectroscopy technique was used to compare the concentration of the iron ions that remained in the solution after galvanostatic analysis in the absence and presence of the hydrazones under different conditions; it was found that the inhibited solution contained lower concentrations of iron ions as compared to the uninhibited solution. The DFT theoretical analysis verified the observation of hydrazone physical adsorption through bonding electrons that obey kinetic adsorption isotherms. It is based on examining the highest occupied molecular orbital−lowest occupied molecular orbital (HOMO−LUMO), the Fukui functions, and the Mulliken atomic charge. Overall, the results suggest that HTZS is a good corrosion inhibitor with a large surface area due to the presence of S, N, and O atoms, allowing for creating a larger surface due to the large molecular volume of atoms protecting against the corrosion process.

Due to its simplicity and eco-friendly, the use of plants to create metal oxide nanoparticles has recently attracted a lot of attention. Consequently, the purpose of this study was to generate CuO NPs utilizing two different techniques, including a synthetic approach and an aqueous extract of Moringa oleifera leaves (M-CuO NPs) (S-CuO NPs). Nanoparticles produced were evaluated by SEM, EDX, TEM and XRD, to considering the creation of CuO NPs and to determine the morphological, elemental constitution and size the sample. The average size 14.95 and 35.73 nm for S-CuO and M-CuO NPs respectively, having potentials for application as inhibitor in corrosion of MS. The inhibition and adsorption properties of prepared M-CuO NPs and S-CuO NPs on MS in 1M HCl were investigated using the wt reduction assessment. The maximal IEof prepared M-CuO NPs and S-CuO NPs was 95.06% and 92.10%, respectively, at 1000 ppm. The IE % improves with greater concentration of the prepared M-CuO NPs and S-CuO NPs. According to the findings, M-CuO NPs are the most effective green potential inhibitor for MS in acidic conditions. It is demonstrated that the Langmuir isotherms are obeyed by the produced CuO NPs and MS substrate.
