The extract of Jamun (Syzygium cumini) seed as green corrosion inhibitor for acid media

The extract of Jamun (Syzygium cumini) seed as green corrosion inhibitor for acid media The corrosion inhibition of mild steel in hydrochloric acid and sulfuric acid solutions by the extract of Syzygium cumini seed was studied using chemical, electrochemical impedance spectroscopy, linear polarization, and potentiodynamic polarization techniques. The inhibition was assumed to occur via adsorption of the inhibitor molecules on the metal surface. The adsorption of the extract on the mild steel surface obeyed Langmuir’s isotherm. The results obtained showed that the extract of S. cumini could act as an effective inhibitor of the corrosion of mild steel in hydrochloric and sulfuric acid media. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

The corrosion inhibition of mild steel in hydrochloric acid and sulfuric acid solutions by the extract of Syzygium cumini seed was studied using chemical, electrochemical impedance spectroscopy, linear polarization, and potentiodynamic polarization techniques. The inhibition was assumed to occur via adsorption of the inhibitor molecules on the metal surface. The adsorption of the extract on the mild steel surface obeyed Langmuir’s isotherm. The results obtained showed that the extract of S. cumini could act as an effective inhibitor of the corrosion of mild steel in hydrochloric and sulfuric acid media.
