Thermodynamic and Kinetic Characterization of Aluminum Corrosion and Inhibition Adsorption of Vernonia Amygdalina Fruit Extract IN 0.5N H2SO4By Arvind Kumar Meena
Abstract: Anti-corrosive efficacy of ethanolic extract of Vernonia amygdalina fruit extract on corrosion of aluminum in 0.5N H2SO4 acidic solution was explored by mass loss measurement at rise in temperature between 303-343 K for 24 hours immersion period. The I.E. (η%) has been noticed prominently high (62.92%) at concentration 0.45% at 303 K. An inhibitor adsorption on the surface aluminum have been found to be best fitted Langmuir adsorption isotherm. It …
