Abstract
Weight-loss method and polarization curve measurement were employed to study the inhibition mechanism of imidazoline derivate for mild steel in acidic solution with H2S.The results show that the derivate can retard the cathodic process,and belongs to the cathodic-type inhibitor.The adsorption of the derivate on the surface of mild steel accords with the amended Langmuir adsorption isothermal equation,and higher temperature will facilitate its adsorption.The changes in the apparent activation energy(Ea) and the pre-exponential factor(A) of the corrosion reaction before and after the addition of inhibitor were also discussed.
