Eco-friendly Corrosion Inhibitor from Tagetes patula L. for Aluminium alloy (3SR) in Acid Fluid Used in Industrial Operations
Abstract
The ability of Tagetes patula L. leaf extract (TPLE) as green corrosion inhibitor for acid corrosion of aluminium in acid fluid (1 M HCl ) was studied using chemical technique. TPLE extract inhibited the acid corrosion of Al
significantly, with about 90 % efficiency at the highest concentration of the extract. The adsorption of the inhibitor molecules on aluminium surface was found to obey Langmuir adsorption isotherm with ∆G 0ads value of 13.01 k J
