要約(英語): Pulsed electric discharge in water has been intensively studied recently for industrial, environmental and biomedical applications as a prolific source of different active species and reactive radicals. The main purpose of this work is to investigate effects of three parameters- such as gap distance, electrode configuration and pulse repetition rate on hydrogen peroxide generation using pulsed discharge in bubbling water. A ceramic filter is employed to isolate both gas and liquid phases and generate bubbles by feeding argon gas through the filter. The experimental results are as follows: the concentration of H2O2 increases significantly with a shortened gap distance, and discharge characteristics change from streamer-like to arc-like discharges depending on the propagation of streamer through bubbles to the ground electrode. An increased yield of H2O2 was also found with treatment time, pulse repetition rate and use of the needle-to-mesh electrode configuration.
