| Abstract: |
| The inhibitive effect against Q235 steel and adsorption behavior of compound inhibitor including imidazoline phosphate and KI was studied in 1 mol/ L HCl solution using weight-loss method, polarization curve and electrochemicalimpedance spectroscopy(EIS)techniques. Results show that the compound inhibitoris mix-type inhibitor which mainly inhibites cathodic process against Q235 steel in 1 mol/ L HCl solution.The inhibition efficiency increases with the increasement of inhibitor concentration. It is seen that the adsorption of compound inhibitor on Q235 steel fits the Langmuir isotherm equation. |
