Water purification by discharge inside bubble in water containing two organic compounds has been investigated. Dichloromethane (DCM) and sodium formate were employed as specimens to evaluate decomposition efficiency. Argon or oxygen gases were injected into the water near the high-voltage wire electrode to generate plasma to identify the dominant reactions of the decomposition of the organic compounds solutions. The DCM was decomposed successfully by injecting argon gas. In contrast, sodium formate was decomposed by injecting oxygen gas. When each gas was injected, in the amount of decomposition of DCM, there was little difference between solution of DCM alone and the solution mixed with sodium formate. On the other hand, the decomposition efficiency sodium formate decreased in the mixed solution in comparison with that in the sodium formate solution. These results indicate that the DCM addition into the sodium formate solution did not affect decomposition efficiency of sodium formate under the experimental condition.
