Abstract
Description
Electro�oxidation and inhibitor performance of copper specimens in 1 M hydrochloric acid solu�
tion was investigated at room temperature by linear potentiodynamic polarization and gravimetric method in
the presence of 2�aminoethanol (A) and N, N�diethylethanamine (D) as an inorganic inhibitor. The effect of
the inhibitory concentration on the corrosion behavior of copper was studied over 288 hrs at 298°K. The
inhibitory efficiency rise up to 96% for single induced and 98% for synergistic behavior. The adsorption
mechanism characteristic was supported by SEM/EDX analysis and adsorption isotherm. From all indica�
tion, the inhibitive efficiency of these compounds majorly depends on their molecular structure and concen�
tration. The blocking effects of the surface interface were also explained on the basis of the inhibitor active
action. 2�aminoethanol and N, N�diethylethanamine inhibits copper in 1 M HCl by strictly affecting both
the anodic and cathodic sites. Portion of the surface covered calculated was also found to follow Langmuir
adsorption isotherm.
