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
mol -1 .
