| Abstract: | The inhibition effects of three kinds of Gemini surfactants on L360 steel in H2S/CO2 solutions were studied by means of static weight loss method,potentiodynamic polarization curves and electrochemical impedance spectroscopy(EIS).The results revealed that the Gemini surfactants showed different inhibition effects,12-2-12 was the best one,and the following was 16-2-16,the performance of 18-2-18 was not obivious.The adsorption of Gemini surfactants on steel could reduce the corrosion of carbon steel in corros... |
