| Description |
The inhibitor performance of chemically synthesized water soluble poly(aminoquinone) (PAQ) on iron corrosion in 0.5 M
sulphuric acid was studied in relation to inhibitor concentration using potentiodynamic polarization and electrochemical
impedance spectroscopy measurements. On comparing the inhibition performance of PAQ with that of the monomer ophenylenediamine
(OPD), the OPD gave an efficiency of 80% for 1000 ppm while it was 90% for 100 ppm of PAQ. PAQ was
found to be a mixed inhibitor. Besides, PAQ was able to improve the passivation tendency of iron in 0.5 M H2SO4 markedly.
