“…At a concentration of 1.2 g/L of TGLE, the greatest inhibitory effectiveness (IE) was measured, which indicated that this was the ideal concentration for corrosion inhibition. Bashire et al 2019, found that raising the concentration of TGLE led to a stronger adsorption of TGLE molecules on the surface of the aluminium, which led to an increase in the surface coverage and a better separation of the aluminium from the sodium hydroxide [15].…”

A kind of tropical hardwood tree called the Tectona grandis tree that is indigenous to India. The name "teak tree" is another common name for this kind of tree. It is a member of the plant family that is referred to as Lamiaceae. The primary purpose of this research is to investigate whether or not the plant extract has a corrosion-inhibiting quality. In this study, an aqueous extract of Tectona grandis leaves, commonly known as TGLE, was employed as a corrosion inhibitor for aluminium (Al) in a solution of sodium hydroxide with a concentration of 1M. The sodium hydroxide solution was prepared by diluting 1M sodium hydroxide with 1M sodium hydroxide. Electrochemical methods, such as Potentiodynamic polarisation (PDP) and Electrochemical Impedance Spectroscopy (EIS), in addition to chemical methods, were used in this study to evaluate the inhibitory effects of this medication (weight loss). A promising inhibitory efficiency (IE) of 80% was achieved with TGLE when it was administered at an optimal dosage of 1.2 g/L; this was found to be consistent across all of the techniques that were used. The results of the trials were combined into an appropriate adsorption isotherm, which allowed for additional study into the inhibitor's method of action to be carried out. In order to investigate the possible influence that temperature may have on the effectiveness of the inhibitor, a temperature range of 303 to 333 degrees Kelvin was investigated. An inquiry of the surface was carried out using microscopic metallurgical research, and the results of this study provided further support for the findings.

“…Charge transfer resistance (Rct), Solution resistance (Rs) and doublelayer capacitance (Cdl) constitute the fundamental electrical equivalent circuit for characterizing the electrochemical performance of a substrate/metal in corrosive solution. The EIS evaluation generated a Nyquist plot, with the imaginary part on the Y-axis and the real component of the impedance on the X-axis [115,116].…”

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.

“…∆G°ads negative values suggest the spontaneity of the adsorption process and the stability of the adsorbed film onto the aluminum surface. It is usually accepted that ∆G°ads values around −20 kJ mol −1 or lower indicate electrostatic interaction between charged metal surfaces and charged organic molecules in the bulk of the solution (physisorption process), while those around −40 kJ mol −1 or higher involve charge sharing or charge transfer between the metal surface and organic molecules (chemisorption process) [35]. The calculated ∆Gads and Kads values are presented in Table 3.…”

The non-toxic anticorrosion properties of nicotinamide have been studied on aluminum in an acidic medium. The techniques included weight loss method, electrochemical measurements, quantum chemical calculations, Monte Carlo simulation, infra-red spectroscopy and scanning electron microscopy. This study gathers information about the inhibitor molecule adsorption onto the surface of metal specimens. Thermodynamic parameters were utilized to predict the adsorption mechanism. The dependence of corrosion inhibition efficiency on various parameters was examined, and it was seen that the increase in the inhibitor concentration and in temperature led to an increase in the inhibition efficiency. The dipole moment and EHOMO-ELUMO influenced the inhibition efficiency, which was observed by quantum chemical studies.
