Abstract

The electrochemical behavior of anthroquinone-2-sulphonic acid (AQS) and the interaction of the heavy metal ions such as Cu2+, Hg2+, Cd2+ and Mn2+ at the glassy carbon electrode in the aqueous alcoholic 0.1M KCl solution is studied through cyclic voltammetry technique. The AQS redox system mediated dioxygen reduction process is explained. The scan rate effect of the AQS, Cu-AQS, Hg-AQS, Cd-AQS and Mn-AQS provides useful parameters such as surface concentration of electroactive species, formal potential of the AQS system, rate constant and electron transfer coefficient number. These parameters conclude that the reduction process of AQS is catalysed by manganese ion and oxidation process is catalysed by the cadmium and mercury ions. Multisweep cycle experiment clearly shows the hydroxylation reaction is occurred at the 6th postion of AQS in the AQS and metal-AQS systems. The semiquinone formation and stabilized by the OH group in the AQS is clearly explained from the appearance of the peak at -0.3V. Except copper, all the metal-AQS system shows semiquinone peak. Thus copper undergo complexation reaction with 6-hydroxydihydroanthraquinone-2-sulphonicacid which is formed at the reduction process of AQS system after the first cycle.
