Abstract

The main objective of this study is to investigate the corrosion inhibition properties of Gardenia aqualla leaf extract on mild steel using weight determination loss method. The corrosion of mild steel was investigated at different concentrations of Gardenia aqualla at temperatures of 303, 313 and 323 K. G. aqualla inhibit corrosion rate of mild steel from 62.4 mm/yr to 6.5 mm/yr, 91.6 mm/yr to 16.6 mm/yr and 113.8 mm/yr to 28.4 mm/yr at 303, 313, and 323 K respectively. The optimum obtained yield in the inhibition efficiency is from 63.8% to 89.5%, 52.5% to 81.9% and 39% to 75% for the various temperatures respectively after an interval of 3 days being in contact in aqueous solution. Langmuir isotherm confirmed that physisorption occurred and it was found that inhibition occurred through adsorption of the constituents present in the leaf of G. aqualla obtained by phytochemical screening.
