چکیده
|
In the present study,the effectiveness of 6-chloroquinoxaline-2,3(1h,4h)-dione (p2) on the corrosion inhibition of mild steel in 1 mol l-1 hcl has been analyzed using weight loss measurements,potentiodynamic polarization,electrochemical impedance spectroscopy and quantum chemical study(dft). this organic inhibitor was characterized by ft-ir,and thermodynamic parameters were calculated. the polarization showed that the inhibition efficiency of compound (p2) was increased with increasing the concentration of p2. the electronic properties obtained using quantum chemical approach was correlated with the experimental inhibition efficiencies.
