Abstract
:
The inhibitive effects of water and alcoholic extracts of Medicago Sative(MS) and Ruta Chalpensis (RC) on the corrosion of steel in 2.0M H2SO4 containing 10% EtOH have been studied using weight-loss(ML), hydrogen evolution(HE), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) techniques. The results showed that the inhibition efficiency increases with the increase of Medicago Sative(MS) and Ruta Chalpensis (RC) concentration, which act as mixed type inhibitors. The inhibition action of Medicago Sative(MS) and Ruta Chalpensis (RC) were discussed in terms of their horizontal adsorption on the metal surface. The adsorption follows Langmuir adsorption isotherm. The effect of temperature in the range (20-60) oC on the performance of the water and alcoholic extracts of MS and RC plants at fixed concentration (1.96x10-2 w/v) of each of them on steel corrosion in 2.0M H2SO4 containing 10% EtOH was also carried out. The studied extracts of (MS) and (RC) show also good inhibition efficiency against the corrosion of steel in H2SO4 at high temperatures.
