| description |
In a quest to develop an effective eco-friendly corrosion inhibitor for aluminium rubber leave and corn cob extract were both tested in 1.0 M H2SO4 and compared. The following techniques were used weight loss, AAS and gasometric technique. SEM was utilized to determine the surface morphology of the inhibitor on the metal surface before and after immersion in the corrosive medium. Three adsorption isotherm models were used to explain the reaction mechanism, results obtained shows that the highest inhibition efficiency for rubber extract was 97.8% while that of corn cob was 92.22%. This shows that rubber extract has a superior protection for alumibium in 1.0 M H2SO4electrolyte. The SEM result shows that the surface morphology of the adsorbent on rubber extract treated surface was better than that of corn cob. The Langmuir and Temkin adsorption isotherm models best explain the reaction mechanism which supports the chemisorption interaction of the inhibitors.
