| Abstract: | The role of
phthalic acid (I) and related compounds, viz., o-phenylenediamine (II) and anthranilic
acid (III) to protect aluminium alloy against corrosion in 0.6 M aqueous sodium
chloride solution is studied using potentiodynamic polarization technique and
impedance studies. The order of inhibition effect of these compounds is found
to be I < II < III. Density functional theory (DFT) has been used to
analyze the characteristics of the inhibition mechanism and to describe
electronic and structural nature of the inhibitor on the corrosion process.
Attempt has been made to correlate the inhibiting properties with the
electronic parameters and molecular area of the inhibitors |
