Electrochemical decolorization of the Reactive Orange 16 was studied using
dimensionally stable Ti/PtOx anode in the chloride containing solution.
Different reaction parameters, agitation speed, applied current, sodium
chloride concentration, and dye concentration was varied and optimum
electrolysis conditions were suggested. The hypohlorous acid was suggested to
be an active species in the electrochemical decolorization. Reaction was also
studied using UV-Vis spectrophotometry, high-pressure liquid chromatography
(HPLC), and total organic carbon (TOC) and total nitrogen (TN) analyses.
Keywords: reactive dye, azo dye, electrolysis, hypochlorite, hypochlorous acid
