Abstract EN
A new corrosion inhibitor namely o-Chloroaniline-N-benzylidene (o-CANB) has been synthesized and its inhibitive performance toward the corrosion of Al-Pure in 1.0 M hydrochloric acid has been investigated.
Corrosion inhibition was studied by chemical method (weight loss) and electrochemical techniques including polarization method and electrochemical impedance spectroscopy (EIS).
The present study has shown that this inhibitor is good in acidic media and the inhibition efficiency up to > 99 % in 1.0 M HCl.
Polarization measurement revealed that the investigated inhibitor is a mixed type with a predominant action on cathode.
Impedance measurement showed that the charge transfer resistance (Rct) increased and double layer capacitance (Cdl) decreased with an increase in the inhibitor’s concentration.
Obtained results about inhibition efficiency from weight loss, polarization study and EIS are in good agreement with each other.
The adsorption of the inhibitor on the metal surface in the acid solution was found to obey Langmuir’s adsorption isotherm.
