Corrosion inhibition effect of Aloe Vera gel: Gravimetric and electrochemical study
E-mail:
Effect of Aloe Vera gel on mild steel corrosion in 1 M HCl medium has been studied using weight loss, electrochemical impedance spectroscopy, and Tafel polarization. These results were supplemented by atomic force microscopy (AFM) and scanning electron microscopy (SEM). This extract is selected for this study in view of its rich source of organic molecules. Tafel polarization studies reveal that Aloe Vera gel extract acts as mixed inhibitor. The activation parameters showed that the inhibitor is adsorbed by both physisorption and chemisorption. The inhibitor showed >90% inhibition efficiency and lowest corrosion rate at optimum concentration of 200 ppm.
