The reactive brilliant blue KN-R solution was decolorized by electrochemical method. The influence of some factors on the decoloration was discussed, including current density, decolorization time, electrolyte concentration, solution temperature, distance of electrodes, pH of solution, stirring speed. And the decolorization process was optimized by orthogonal experiment. The results show that, the optimum decolorization process conditions of reactive brilliant blue KN-R solution by electrochemical method are as follows: current density 55 A/m2, decolorization time 25 min, electrolyte concentration 30 g/L, electrodes distance 7 cm, room temperature, dye solution original pH value 6, stirring speed 60 r/min. The reactive brilliant blue KN-R solution can thoroughly be decolorized under above conditions. On the other hand, the decolorization process is simple, perfect effect, energy saving and environmental protection.
