Decolorization and mineralization of an anthraquinone dye, C.I. Reactive Blue 19 (RB19), by single ozonation, single UV radiation and ozonation combined with UV radiation (O3/UV) was carried out in a laboratory-scale experiment. O3/UV treatment resulted more effective for RB19 mineralization than the other two methods. The effect of several operational parameters, including initial dye concentration, pH, ozone dose, and UV radiation on the degradation of the dye and reduction of total organic carbon (TOC) was investigated. Major intermediates of RB19 degradation were identified by gas chromatography/mass spectrometry (GC/MS).
