Abstract
Polarographic current-potential characteristics for the anodic behaviour of 8-hydroxyquinoline (QH) in a pH ~ 5 aqueous AcOH-AcONa buffer have been examined in detail at low concentrations. The electrode reaction is 2 Hg + 2 QH ⇋ Hg2Q2 + 2 H+ + 2 e. The study of the polarographic wave has been performed introducing the Frumkin isotherm in the treatment of adsorption. Also, the inhibition of electrode process due to the films formed on electrode surface has been discussed.Keywords
