摘要：

Degradation of complex organic dyes by pulsed streamer corona discharge in water has been investigated using a ring-to-cylinder electrode geometry system. The obtained result shows that the efficiency of the decoloration depended on the initial pH of solution and the decoloration rate was higher at lower initial pH value. In the case of hydrogen peroxide addition, the decoloration rate increased due to the reactions of dye with hydroxyl radicals formed by photo- dissociation of hydrogen peroxide in the plasma discharge channels. However, the reactor with two rings was more effective than that of one ring for the decoloration due to a larger volume occupied by the streamer plasma channels in water.
