摘      要：The effect of ultraviolet irradiation(UV),ozonation and the combined UV/O systems on the decolorization and degradation of methyl orange,performed in a laboratory scale reactor,was studied. Decoloration efficiency,UV-vis spectrum,chemical oxygen demand(COD),mass spectrum(MS) and total organic carbon(TOC) analyses were *** oxidative processes including ultraviolet irradiation(UV),ozonation(O) and the combined UV/O system were assessed to select the most appropriate oxidative process in terms of methyl orange aqueous solution treatment and special
