POLY-0-AMINOPHENOL OBTAINED AT HIGH POTENTIALS BY CYCLIC VOLTAMMETRY ON SN0(2): F ELECTRODES: APPLICATION IN QUANTITATIVE DETERMINATION OF ASCORBIC ACID

In the present work the obtention of poly-o-aminophenol (POAP) at high potentials on conducting glass (Sn0(2): F) is reported. The synthesis was carried out by continuous potential cycling in a 1 x 10-3M o-aminophenol (OAP), 0.1 M hydrochloric acid, and 0.1 M potassium chloride solution between-0.2...
