Resumo: Plant extracts containing heteroatoms can be used as corrosion inhibitors as they are non-polluting, cheap and eco-friendly. The present work focuses on Asparagus Racemosus (Shatavari) as a corrosion inhibitor of aluminium in acidic medium. The techniques that have been used include weight loss method, quantum chemical analysis and scanning electron microscopy. It was seen that at 4000 ppm concentration of inhibitor the corrosion inhibition efficiency was 72.28%. The inhibition efficiency increased with increase in concentration. The best description of adsorption isotherm was seen to follow Langmuir adsorption isotherm. In order to elucidate the reactivity and molecular structure of inhibitor, quantum chemical parameters were utilized. The surface properties of the metal specimen were determined by SEM.
