| Research Abstract |
The characteristics of discharge plasma generated above water, produced radicals by the plasma and decomposition characteristics are investigated to develop VOC (Volatile Organic Compound) treatment using the discharge plasma. The optical emission from discharge plasma generated above a water surface are measured, and then electron temperature Te and density ne, which show fundamental property of electrons in the plasma, are deduced. Radicals produced in an atmospheric DC corona discharge above water in Ar-O_2 are investigated by in-situ infrared absorption spectroscopy. HO_2 radicals found to be produced in the discharge plasma. By-products from phenol by exposure of pulsed-discharge plasma above a phenol aqueous solution are investigated by gas chromatograph mass spectrometry, and the decomposition process of phenol is deduced.
