Abstract The polarographic and cyclic voltammetric behaviour of (2-hydroxyphenylazo)-4- benzenesulfonamide and some of its derivatives have been studied in Britton-Robinson buffer series containing 30 vol.% of DMF. Over the entire pH range (2-12), the reduction pathway occurs through an irreversible 4-electron step corresponding to the reduction of N= N center to the amine stage. The voltammograms recorded in acidic and alkaline solution ...
