要約(英語): A method for decomposing persistent organic compounds in water by DC corona on water was investigated. The acetic acid as a persistent material was decomposed by corona discharge in oxygen 4 mm away from the surface of the water. The acetic acid in 10 ml solution was a concentration of 9.6-207 mg/l. The number of electrodes where the corona was generated was 4 or 8, the voltage was between 6.2 kV and 9.2 kV, and the current was between 0.09 mA and 0.34 mA. As the voltage and the number of discharge electrodes increased, the decomposition rate increased. The maximum decomposition speed of 4.8 µg/min was obtained with 8 discharge electrodes in initial concentration 20 mg/l of acetic acid. More numbers of the electrode were effective for the decomposition of the acetic acid in the equal discharge power.
