| The effect of Opuntia ficus-indica (Nopal) as green corrosion inhibitor for carbon steel in HCl 1M solution has been investigated by weight loss measurements, potentiodynamic polarization curves and electrochemical impedance spectroscopy. Also, scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). The inhibitor concentrations used ranged from 0 to 300ppm at 25, 40 and 60ºC. The results indicated a) the inhibition efficiency increases with increasing extract concentration and b) the inhibitor act as a mixed-type inhibitor. The inhibition behavior has been associated with adsorption effects. In fact, the adsorption of the inhibitor on the steel surface follows the Langmuir adsorption isotherm, indicating monolayer adsorption. On the whole, the best efficiency was obtained at 300ppm and 60ºC. | |
