Decolorization of textile dye CI Basic Yellow 28 with electrochemically generated active chlorine
Abstract
Reaction of the indirect electrochemical decolorization of cationic textile dye CI Basic Yellow 28 with electrochemically generated "active chlorine" has been studied, using UV-Vis spectrophotometry, ion chromatography, organic carbon analysis, and cyclic voltammetry. Decolorization has been investigated on Ti/PtOx anode for different currents in the range of 50-200 mA, sodium chloride concentration in the range from 5 to 25 g dm(-3), and dye concentration from 10 to 70 mg dm(-3). The optimum electrolysis conditions and possible active species have been suggested.
