| Abstract | The oxidation behavior of ethylene and methanethiol were investigated in the systems of ultraviolet (UV) light/hydrogen peroxide aqueous solution and UV/hydrogen peroxide aqueous solution/wire mesh to evaluate the usefulness of UV irradiation for the oxidation of volatile organic compounds. The light induced chemical absorption of ethylene was observed. UV irradiation induced the chemical absorption of ethylene; ethylene was not oxidize directly by UV irradiation, and it did not dissolve into hydrogen peroxide aqueous solution in the absence of UV irradiation. Ethylene was converted to intermediates that dissolve in the liquid phase. Carbon dioxide evolved drastically after the disappearance of ethylene in the gas phase. The methanethiol concentration decreased drastically by UV irradiation in the UV/hydrogen peroxide system while the intermediates produced by the direct photodecomposition tended to remain in the gas phase. The UV/hydrogen peroxide/wire mesh system accelerated the oxidation of the intermediates in liquid phase as well as the intermediates in the gas phase according to the photo-Fenton reaction. |
