Effect of Temperature on Adsorption Behaviour and Corrosion Inhibitive Performance of Aqueous Extract of Green Inhibitor Leaves in Mixed Acids

Abstract: Leaf extract of green inhibitor (commonly known as Borrachero or Morning Glory) is found to be efficacious on corrosion of mild steel in mixed acid solution in paste form using traditional weight loss measurements techniques. For different solution concentrations in the form of paste at various temperatures, corrosion inhibition efficiency of Borrachero leaf extracts was assessed with the help of weight loss measurements. For comparison, date of rust dissolution in liquid state has also been furnished. Different temperature conditions were appraised for the sake of overall inhibitor efficiency. From the results, Borrachero leaves have a good potential, at certain range of temperature, as eco-friendly, green, corrosion inhibitor.
