Abstract:
The inhibitive effect by salicornia extract for carbon steel in 1M H2SO4 solution was investigated using
gravimetric methods and electrochemical techniques at room temperature. The results showed that the presence of
salicornia extract inhibited the corrosion of carbon steel and that the inhibition efficieucy depended on the
concentration of the inhibitor as well as on the time expouser . The dry salicornia extract and the protective film have
been analyzed using Fourier transform infrared FTIR spectroscopy. Inhibitive effects of the extract obtained from
impedance and polarization measurements were found increase with increase concentration of inhibitor. The
adsorption of the inhibitor characteristics were approximated by Langmuir adsorption isotherm at all concentration at
25 ?C. On the other hands, the metallurgical microscopy was used to observations the metallographic.
