Summary form only given. Pulsed barrier discharge is generated in a gas-liquid two-phase flow for decomposing persistent substances in water. This new method is proposed to extend the interfacial area between the nonthermal plasma and the treat water for efficient decomposition of persistent materials. Acetic acid solution as a persistent substance is filled in a plasma reactor that consists of two...
Summary form only given. We discuss a new scheme to create microplasmas by pulsed discharge in air with an ethanol filament that is created by electrostatic force between electrodes. We reported previously to use a droplet as the initial matter for the generation of microplasmas with liquid. These plasmas were operated by pulsed discharges, owing to the preparation of the liquid filament. The discharge...
Summary form only given. Water treatment by atmospheric oxygen plasma was examined for decomposing persistent materials such as dioxin. In the previous experiments the acetic acid (CH3COOH) as an alternative to the dioxin was successfully decomposed by the combination of fast oxygen flow and a DC driven micro hollow cathode discharge (MHCD). Meanwhile no decomposition was observed with ozone injection...
