Influence of Current and Kind of Gas on the Hydrogen Peroxide Generation in the Water Solutions

Popis výsledku v původním jazyce

This contribution presents results of underwater electric discharge created in the bubbles in NaH2PO4.2H2O solution. This discharge configuration is relatively new one and fully combines both gas and liquid phase discharges. The gas bubbles are introduced into the system by thin stainless steel capillary that plays simultaneously a role of HV pin electrode; water solution of low conductivity up to 0.05 mS is grounded. Thus the HV pin electrode is covered by thin gas layers and the discharge is generatedin the gas phase in pin to plane configuration. The discharge streamers (plasma channels) generated in the gas phase are long enough (up to 1 cm) and thus they introduce into the liquid phase and further propagate in it. The streamer length as well as their density is growing with increase of the applied voltage. The AC voltage between 2.0-3.0 kV was used in the contemporary experiment. Discharge current was varied from 20 to 30 mA, lower currents of 10 mA and 15 mA didn't allow stable
