Inhibition Mechanism of Imidazoline Amide in CO2 Solution
Abstract:
The inhibition mechanism of imidazoline amide(IM) in CO2 solution has been studied by electrochemical techniques including electrochemical impedance spectrum and polarization result measurements. It is shown that the inhibition of IM is due to the negative catalytic effect on the iron. Its adsorption obeyed the Langmuir isotherm. The positive shift over to adsorption potential is the main reason of desorption of IM on the anode, which increases the interface capacity and decreases the transmission resistance.
