Effect of Chlorine Dioxide on Decoloration of Reactive Dye

Article Preview

Abstract:

As an important oxidants, Chlorine dioxide was more useful in the decolorization of Reactive Red KE-3B, Reactive Blue KN-R, Reactive Red X-3B and Reactive Blue X-BR. It was found that the optimal pH=8,the optimal initial dosage of ClO2 and reaction time were 60 mg*L-1 and 15 min, respectively. The optimal reaction temperature of dyes were 80°C. Chlorine dioxide seems to be viable method for achieving significant decolorization of dying industry wastewater.
