“…Subsequently, the adsorption of inhibitor on the substrate surface was studied as a function of the applied potential. The results demonstrated that the concentration of adsorbed inhibitor on the metal surface increased as the positive charge on the surface increased 73,74 .…”

“…Concentrated extracts are then diluted to prepare inhibitor solutions of various concentrations. In one particular instance, sulfated fatty acid (SFA) inhibitors were synthesised via hydrolysis of corn oil and then using the products in a sulfating treatment 50 , while another group of researchers treated the plant extract with a reducing agent to make a water-soluble inhibitor solution 73,74 .…”

The use of corrosion inhibitors is a cost-effective corrosion mitigation strategy for carbon steel. There is an increased focus on developing and using low-cost, biodegradable and environmentally friendly inhibitor formulations. Plant-based extracts have been evaluated in many studies using a multitude of electrochemical methods and characterisation techniques. Although plant extracts appear as promising alternatives for commercially synthesised inhibitor formulations, a significant amount of optimisation is required. The majority of the research on plant extracts does not elucidate the effect of other synergistic combinations in commercial inhibitor formulations. Therefore, further development of plant extracts as corrosion inhibitors is of significant interest.
