چکیده
|
In this paper,the inhibition ability of poly(1-phenylethene) against the carbon steel corrosion in 1.0 m hcl solution was studied at different temperatures range from 298 to 328 k using weight loss,potentiodynamic polarization and electrochemical impedance spectroscopy (eis). it was found that the studied compound exhibited a very good performance as inhibitor for carbon steel corrosion in 1.0 m hcl medium. the obtained thermodynamic adsorption parameters (δg* ads,δh* ads,δs* ads) indicated that this polymer retarded both cathodic and anodic processes through physical adsorption and blocking the active corrosion sites. it is found also that this compound obeyed the langmuir’s adsorption isotherm. © 2016 by cee (center of excellence in electrochemistry).
