“…Methanol was evaporated from the soaking solution of oak galls using an IKA rotary evaporator (Germany). Finally, the yellowish powder extract was collected from the inside of the flask of the evaporator and used for the study as shown in Figure 2 9,15,21,22 . Three concentrations (2, 4, and 6%) with absolute methanol were prepared for this study.…”

The aim of this work is to investigate the effectiveness of oak galls extract (OGE) as a green corrosion inhibitor from natural resources to prevent the corrosion of archaeological iron artifacts in atmospheric environments. The inhibition efficiency has been evaluated by measuring the weight loss of the treated coupons after exposure to 85% RH in a humidity chamber, Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. Also, the morphology of an adsorbed film on the surface was investigated by scanning electron microscopy and optical microscope. The influence of OGE on changing the original appearance of the surface was also evaluated using visual examination and colorimetric measurements. The measurements results revealed that OGE gave high inhibition efficiency reaching approximately 95% of 6% concentration. Based on the study results, OGE can be proposed as an efficient green inhibitor for iron artifacts.

“…However, the majority of organic species are environmental pollutants and expenditure in the nature. Hence, development of new corrosion inhibitors with zero environmental effect to be more desirable and important, which is called as green or eco-friendly corrosion inhibitors [4][5][6][7]. Many corrosion scientists reported expired drug as environment friendly corrosion inhibitors for different metals in the various environments.…”

The present study explores the green corrosion inhibition property of expired Lorazepam tablet on the mild steel (MS) in 3M HCl solution using gravimetric (mass loss), atomic absorption, Tafel plot, electrochemical impedance, quantum chemical, and scanning electron microscopy (SEM) studies. It is found that; expired Lorazepam tablet shows the robust corrosion inhibition property (protection efficiency = 90%) on the MS at 0.4 g/L of expired Lorazepam drug (observed from the gravimetric studies) at 333 K with a contact time of 3 h. The significant enhancement in the protection performance of the expired Lorazepam tablet has been observed by atomic absorption spectroscopy technique. The results of Tafel plots show that, the presence of the expired Lorazepam tablet of different concentration decreases the both cathodic and anodic processes at MS in the 3M HCl solution by blocking the MS active sites and behave as a mixed mode corrosion inhibitor. Electrochemical impedance studies show that, increase in the amounts of expired Lorazepam tablet increases the charge transfer process at MS-HCl interface. The electron transfer nature of the expired Lorazepam tablet on the MS surface was confirmed from the Quantum chemical studies. The adsorbed invisible layer over the surface of MS was scrutinized by scanning electron microscopy technique.

The inhibition of copper corrosion by expired Famotidine drug in the 3 M HCl solution was examined through weight loss and atomic absorption spectroscopy studies. Weight loss studies show that, the increased in the expired Famotidine drug amounts generally enhances the protection efficiency of the corrosion inhibitor. Atomic absorption spectroscopy study indicates that, the weight loss of copper metal decreases with a rise in the concentration of the expired Famotidine drug in the 3 M HCl solution. The protective film generated on the copper surface in the 3 M HCl solution responsible for the prevention of copper metal corrosion in the acidic system. The examined drug may be useful to solve the metal dissolution problem in many industrial units.
