Study of Green Corrosion Inhibitor of Aegle marmelos Leaves Extract in Acidic Medium

Abstract:

Corrosion is an inevitable process of deterioration of metal but it can be slowed down using inhibitors, enhancing the durability of the metal. In the present study, the aqueous extract of Aegle Marmelos Leaves from surrounding area were tested as green corrosion inhibitor for aluminium metal in 1M H₂SO₄ acidic medium. The leaves extract characterization was analyzed using Fourier Transform Infrared Spectroscopy (FT-IR), the surfaces of Aluminium Sheets were examined using scanning electron microscopy (SEM) and atomic forced microscopy (AFM). Different techniques like weight-loss analysis, UV-VIS studies, pH are done to study for inhibition efficiency. At different temperatures the inhibition efficiency is tested and results showed a good restrain approximately to 81% at 90% (v/v) of inhibitor solution in H₂SO₄ acidic medium.
