Cyclic voltammetric study of anthraquinone-2-sulfonate in the presence of Acid Yellow 9

Add time:08/04/2019    Source:sciencedirect.com

The electrochemical reduction of anthraquinone-2-sulfonate (AQS) has been examined in the presence of an azoic dyestuff (Acid Yellow 9, 4-amino-1,1′-azobenzene-3,4′-disulfonic acid, sodium salt) in alkaline solution. The dianion of the anthrahydroquinone-2-sulfonate (AQS2−) formed by cathodic reduction reacts with Acid Yellow 9 to regenerate AQS and yields the reduced dyestuff. The catalytic currents generated due to the chemical reaction between the AQS2− and the dyestuff have been used to estimate the rate constant of the reaction.
