要約(英語): Pulsed discharge in bubbles generated by pulsed power source is applied to water treatment containing persistent substances, which are mainly organic substances in water and have recently resulted in environmental damage. Humate, the target in this study, is one of the persistent substances.A Blumlein type pulse forming network (B-PFN) is provided in the work. The reactor is constructed by a cylinder equipped with a pair of electrode, which are an injection needle and a spiral electrode. The gas used for bubbles are helium, oxygen and nitrogen. In this study, the absorbance from 280 to 600 nm in the wavelength and the total carbon concentration of the humate solution is measured by a spectrophotometer and a total organic carbon analyzer. From the results, the decrease of the absorbance in humate solution is observed and elucidated certain variation of chemical bonding condition in the humate solution. The decreasing rate of the humate solution by pulsed discharge in nitrogen bubble is larger than the pulsed discharge in oxygen and helium bubbles. The organic carbon concentration has decreased by the pulsed discharge in oxygen and nitrogen bubble.
