| Abstract | ||
| The gemini surfactant polyamide derived from Hexa methylene diamine and ethylene diamin tetraacetic acid [(2,2'-1,22-diamino-8,15-dioxo-7,10,13,16-tetraazadocosane-10,13-diyl) diacetic acid ] was synthesized according to the previous our work [1] . A series of electrochemical measurements, including corrosion potential and corrosion current has been made on polyamide-coated carbon samples in corrosive environment. Results showed that polyamide can offer some degrees of protection in the corrosive environments. The thermodynamic functions of dissolution, activation energy and adsorption processes were calculated and discussed. Adsorption of the inhibitor was found that a follow the Langmuir adsorption isotherm. The corrosion study of this polymer outline that a new surfactant has a good resistant to the corrosion of carbon steel in 1 M solution of HCl. | ||
