Study on Synthesized Polyamide Surfactant as a Corrosion Inhibitor
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.
Keywords: Surfactant; Polyamide; Corrosion.
