要約(英語): The influence of the pH of aqueous solution on the decomposition of acetic acid was investigated for water treatment using a pulsed streamer discharge under atmospheric pressure. The acetic acid present as persistent organic compounds in the aqueous solution was decomposed by the pulsed streamer discharge on the water surface. Oxygen and argon were used as gases to envelope the water surface. When oxygen was used, the decomposition efficiency (the amount of decomposition of acetic acid per energy consumed) strongly depended on the pH of the solution, i.e., the higher the pH, the higher the efficiency. However, the discharge energy was unchanged in both oxygen and argon when the pH of the solution changed. It was found that the decomposition efficiency was improved when the initial pH of the aqueous solution was higher, namely, in oxygen.
