INVESTIGATION OF PULSED BARRIER DISCHARGE IN WATER-AIR GAP

This article presents the results of the use of a pulsed dielectric barrier discharge with water electrode and diaphragm. The spectroscopic and electrical investigations of such discharge were conducted. The ozone concentration in an aqueous solution comprised 0.7 mg/l with high-voltage pulsed power at 120 W. The discharge reviewed emission spectrum lines of molecular nitrogen and hydroxyl radicals in the range of 200…800 nm in the water-air gap. The intensity changing of luminescence lines of ОН and N2 singles depending on the applied voltage and discharge gap has been determined. Aqueous solution of indigo was used in order to determine the impact level on the organic material. Experiments on inactivation of test E. coli cultures have been carried out. PACS: 52.80.Hc, 41.75.Lx, 41.60.Bq.
