Recent Advances on the Corrosion Inhibition Behavior of Schiff base Compounds on Mild Steel in Acidic Media

Abstract Corrosion inhibitors for mild steels subjected to aggressive media are needed by various industries, especially in power plants, petrochemical, automobile, and pharmaceutical. Accordingly, Schiff bases as a category of organic inhibitors have demonstrated efficient protecting activity in corrosive environments. This review focuses on the corrosion inhibitory performance of different Schiff bases for mild steel in acidic media and underlines the reports on which the protecting efficiency and applicability of Schiff bases have been affected by introducing different reagents as well as considering the environmental and structural issues. Therefore, discussed influential factors could endow approaches to design and apply more effective Schiff bases in the corrosion field, particularly alternatives under ecological guidelines and high inhibition efficiency.
