| Abstract: | The scope of polarography and voltammetry in analyzing azo dyes, anthraquinone-, polycondensed aromatic and vat dyes, di- and triarylcarbonium and heterocyclic dyes, nitro-, nitroso dyes and nitro intermediates, intermediates such as sulphonation products of 2-naphthol, diazonium salts and diazonium compounds is outlined. In view of much tougher future toxicological and environmental constraints and new outlets for dyes in modern high technology industries, polarography and voltammetry may find new and wider application and recognition. |
