Abstract EN
The influence of natural occurring extract of Chenopodium Ambrosioides (CAE) on the corrosion inhibition of carbon steel in sulfuric acid solution is studied by the weight loss method, potentiodynamic polarization and impedance spectroscopy (EIS) measurements.
The experimental results reveal that extract has a good inhibiting effect on the metal tested in 0.5 M H2SO4 solution.
The protection efficiency increases with increasing inhibitor concentration to attain 94% at 4 g/l.
Potentiodynamic polarization studies clearly reveal that it acts essentially as a cathodic inhibitor.
EIS results show that the change in the impedance parameters (Rt and Cdl) with concentration of extract of Chenopodium Ambrosioides is indicative of the adsorption of molecules leading to the formation of a protective layer on the surface of carbon steel.
The efficiency decreases with temperature.
The adsorption of Chenopodium Ambrosioides extract is found to obey the Langmuir adsorption isotherm.
The activation energies and enthalpies of the corrosion process of carbon steel in acidic medium were determined.
