Abstract

The advanced oxidation of aromatic compounds in aqueous solution has been investigated using a multi-gas, dielectric barrier discharge, and the degradation rate was measured by high performance liquid chromatography (HPLC). In the degradation experiment of 2,5 - DNP, an accelerated degradation pathway was suggested in the transient state, using the molecular orbital calculation of the enhancement of the degradation of oxidation depending on the para-position of nitro-groups. From the nature-friendly technological point of view, a growth of the radish sprout in the hypo-culture was tested after the pH-neutralization of the air-plasma treated water.
