要約(英語): Oxidation of simulated soil using pulsed discharges is investigated. Glass beads are used as the simulated soil for evaluation of an oxidation ability of the discharges. Indigo carmine solution and Fusarium oxysporum are used to evaluate the oxidation ability, and are mixed with the glass beads. The moisture contents of the simulated soils with the indigo carmine solution and with the Fusarium oxysporum suspension are fixed at 9.1% and 16.7%, respectively. A plate to wire electrodes is used to generate discharges on the surface of the simulated soil. The high voltage pulses with voltage of 13 kV and pulse width of 250 ns are generated using a magnetic pulse compression circuit, and are applied to the wire electrode with pulse repetition rate of 2000 pps. The decolorization rate in the case of 16.7% is much lower than that of 9.1%. The deactivation effect of Fusarium oxysporum in case of 9.1% is higher than that of 16.7%.
