ELECTROCHEMICAL REDUCTION BEHAVIOR OF 1-AMINO-9,10-ANTHRAQUINONE

The electrochemical reduction behaviour of 1-amino-9,10-anthraquinone has been studied by employing d.c. polarography cyclic voltammetry, a. c. polarography and differential pulse polarography in the supporting electrolytes of pH ranging from 2.0 to 12.0 Millicoulometry is employe d for the determination of number of electrons involved in the electro de process. Diffusion coefficient values and forward rate constant val ues are evaluated. The nature of the electrode process and reduction m echanism have been presented. In this communication a detailed polarog raphic determination procedure has been described, based on the well-d efined cathodic peaks obtained for the electroactive species.
