Effects of polyethylene glycol (PEG) on the corrosion inhibition of mild steel by cerium nitrate in chloride solution

Acrylonitrile-butadiene-styrene (ABS) is a common waste polymer by-product from industry. Outdated medicines are usually discarded and could be a valuable asset for other applications such as metallic corrosion inhibition. The aims of the present work is to manufacture a recycled ABS polymer doped with outdated lansoprazole medicament as a corrosion protection composite coating. It was applied to mild steel and immersed in chloride solution, and evaluate its possible corrosion protection properties using different electrochemical techniques. The manufactured coating presents good corrosion protection properties showing an 80% efficiency as a function of time of immersion in the aggressive solution.

Apricot Pomace

Purpose This paper aims to investigate influence of extraction solvent on the efficacy of apricot pomace extract (APE) as a sustainable corrosion inhibitor for mild steel in sodium chloride solution. Design/methodology/approach The chemical profiles of the extracts were analyzed using gas chromatography–mass spectrometry. Total phenolic, total flavonoid content and antioxidant properties of the extracts were determined. Besides, gravimetric, potentiodynamic polarization and atomic force microscopy were used to study the corrosion inhibition. The effect of immersion period on inhibition efficiency was evaluated. The reaction mechanism of the inhibitor was also discussed. Findings Corrosion inhibition decreasing is in the following order: solution of 2-propanol/ethanol apricot pomace (E/PAPE) extract > ethanol (EAPE) > 2-propanol (PAPE). The gravimetric, polarization measurements and surface analysis revealed that the growth of inhibitory properties is prolonged, and corrosion rate reduction after 40–48 h of exposure was studied. Practical implications APEs play an important role in the corrosion inhibition of mild steel in sodium chloride solution. Moreover, its application is potentially possible in industries. Social implications The results contribute to the integrated valorization of food waste. Originality/value The different compositions of the conversion/oxidation products of organic substances in solution were studied. The formation of polymerized flavanol-aldehyde adducts and oxidized quinone compounds or tautomers structures because of extract transformation in water causes main corrosion reduction in 40–48 h.
