“…72,73 The best way to describe CO-GO adsorption on carbon steel was found for the Langmuir adsorption isotherm. This isotherm could be expressed as 74,75 θ = + C K C 1 ads (10) where Θ is the degree of surface coverage, C inh is the concentration of inhibitors, and K ads symbolizes the equilibrium adsorption constant, which is graphically calculated from the plot displayed in Figure 7. The obtained value of K ads was used to derive the standard adsorption free energy ΔG ads 0 as shown below 76,77 where R, T, and C H 2 O are the gas constant, the temperature of the system, and the concentration of the water molecules (1000 g/ L), respectively.…”

This study aims to synthesize new chalcone oxime functionalized graphene oxide (CO-GO) and investigate the enhancement in corrosion protection. The morphology and structure of the synthesized CO-GO have been characterized by elemental analysis: Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), and scanning electron microscopy (SEM). Moreover, the effectiveness of corrosion inhibition was investigated by utilizing electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP). The results of the above analyses demonstrate that CO-GO has an outstanding corrosion inhibitor performance of up to 94% and acts as a mixed-type inhibitor with a primarily anodic action. The effect of temperature on a carbon steel surface indicates that the tested composites are chemisorbed. A few techniques were able to provide surface characterization such as scanning electron microscopy and ultraviolet (UV)−visible spectroscopy to confirm inhibitor adsorption on the carbon steel surface.

“…where η Fe , χ Fe , and η inh , χ inh denote respectively the global hardness and the electronegativity of Fe and the prepared compounds. 77 MC simulations were used to investigate the adsorption ability of Pz1 and Pz2 on the Fe surface by calculating their adsorption energy. Fe(110) plane was selected to perform such adsorption imitations as it represents about 63% of the main crystal growth plane for Fe crystal, in addition, it is a bulk terminated plane without any further surface reconstructions.…”

The inhibitory impact of low-cost synthesized pyrazoline derivatives named Pz series ( Pz1 and Pz2 ) on the corrosion of API 5L X60 carbon steel in 5 M HCl was inspected to serve as corrosion inhibitors against such a solution for its usage in the oilfield well acidization process. Also, the same compounds were unitized as biocides for sulfate-reducing bacteria (SRBs) to inhibit the microbial-induced corrosion effect. This study was conducted via several electrochemical techniques, namely, electrochemical potentiodynamic polarization (EP) and electrochemical impedance spectroscopy (EIS), in addition to computational density functional theory (DFT). The inhibition efficiency (IE) of Pz series on the corrosion of 5L X60 carbon steel in 5 M HCl was found to increase whenever the Pz series molecule concentration was increased. EP measurements revealed that Pz1 and Pz2 have both cathodic and anodic features (mixed inhibitor) and their corrosion IEs were around 90%. The physicochemical properties of the Pz1 and Pz2 compounds were studied using Langmuir adsorption isotherms, where the equilibrium adsorption data were found to follow it accurately. EIS outputs were found to comply with the values obtained from EP. Scanning electron microscopy was used to examine the topographic anisotropy between the inhibited and uninhibited 5L X60 carbon steel samples to double-check the electrochemical findings. DFT calculations and Monte Carlo simulations were utilized to predict the behavior of inhibitors and to rationalize the experimental results. The serial dilution bioassay technique was used to assess the Pz series as potential biocides to counter the effect of SRBs in compliance with the TM0194-2014-SG standard test method, and the results showed the potency of Pz series in inhibiting such bacterial growth.

Over the past decade, green chemistry has been emphasizing the importance of environmental sustainability and human health, aiming to minimize toxins and reducing wastes in an economically beneficial manner. The field of metallic materials deterioration, generally faced by the utilization of toxic compounds, discovered a promising research field in green chemistry. The application of inhibitors is a well-known strategy when metal corrosion needs to be avoided, prevented, controlled or mitigate. Green inhibitors are readily available, biodegradable, ecologically acceptable, sustainable and renewable sources. Their esteem broadens the numerous ranges of potential applications in various sectors besides “waste to energy” in the context of a circular economy. Extensive research on various biomass wastes such as corn stalks, nutshells, straw, forestry residue and plant waste-derived inhibitors tremendously has been utilized in corrosion mitigation in different industries to sustain the environment. All the mentioned aspects are the topic of this current review, which is meant as constructive criticism to spotlight the use of biomass waste as efficient green inhibitors in order to re-evaluate their viability and debate prospective research in the field, which is still lacking justification. As a result, this article aims to solve two current problems; waste and corrosion which will benefit both the environment and industry.
