Generation of Oxidants with a Foaming System and its Electrical Properties

Abstract

This works reports on electrical discharge performed in a foaming environment. This new method allows for an effective treatment of polluted gas by contacting the large streams of gas with small amount of liquid. The possibility of generation of oxidants in the foaming column was examined. Hydrogen peroxide (H₂O₂), hydroxyl radicals and the small amount of ozone were generated in the foam. It was possible to obtain 40 mgH₂O₂/dm³ at 14.5 kV of applied voltage and 5 dm³/min oxygen substrate gas flow. In case of air the maximum concentration was 35 mgH₂O₂/dm³ in the same applied voltage and gas flow conditions.
