| Abstract Scope |
Chemical inhibitors play an important role in protection and mitigation strategies to retard corrosion, however, their use can cause negative effects on the environment. Due to this, the use of plant extracts as corrosion inhibitors has been suggested since they are non-toxic, biodegradable and abundant in nature. Aloe Saponaria gel was used as a green corrosion inhibitor of carbon steel in 0.5 M HCl acid medium. The corrosion inhibition performance was investigated by electrochemical impedance and potentiodynamic polarization in the absence and presence of the inhibitor, in different concentrations (10, 20, 30% v/v), at the following temperatures: 298, 308, 315 and 323 K. The trend is observed that the higher the inhibitor concentration, the lower the corrosion rate, this is due to the adsorption of organic matter creating a cover on the surface of the steel. |
