GREWIA TILIAEFOLIA BARK EXTRACT AS GREEN INHIBITOR OF MILD STEEL C ORROSION IN SULPHURIC ACID MEDIUM
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 6
Abstract
This paper presents the inhibitory properties of Grewia tiliaefolia bark extract on the corrosion of mild steel in sulphuric acid medium. The corrosion rates and inhibition efficiencies were evaluated by weight loss measurements. The adsorption of inhibitor obeyed Langmuir isotherm and the negative values of Gibbs energy indicate the nature of interactions between inhibitor molecules and metal surface. Further, the inhibition effect was proved by FTIR spectroscopy, scanning electron microscopy and energy dispersive X - ray analysis.
