Water purification by discharge inside bubble in water containing organic two dyes has been investigated. Indigo carmine and azo phloxine were employed as specimens to evaluate decomposition efficiency. Oxygen or argon gases were injected into the water near the high-voltage wire electrode to generate plasma to identify the dominant reactions of the decolorization of the dye solutions. The energy efficiencies for decolorization of two dyes in single dye solutions were almost same in the case of argon injection. Indigo carmine was decolorized with higher energy efficiency than that of azo phloxine in the case of oxygen injection in single dye solution. Indigo carmine and azo phloxine in the two dyes mixing solution were completely decolorized. Indigo carmine was preferentially decomposed in the case of the mixed solution. These results show reaction rates of indigo carmine and chemical species such as ozone and hydroxyl radical are much higher than that of azo phloxine.
