The potency of Indian snakeroot, Rauvolfia serpentine, as an anti-corrosion spray

Abstract

This study evaluates the effectiveness of Rauvolfia serpentine (Indian Snakeroot) as an anti-corrosion spray on mild steel sheets using gravimetric analysis and comparative tests. The tests were performed in selected environments, including freshwater, and saltwater, but focused more on the results in freshwater. Three pieces of mild steel sheets measuring 5.5cm² surface area were used for this experiment and studied in weighing and re-immersing. It was observed that the corrosion rate increases with time exposure to the corrosive medium in the presence and absence of the extract. If the surface was completely sprayed and the percentage of adsorption rose simultaneously, the Rauvolfia serpentina extract would result in a retardation of the mild steel's corrosion rate.
