| Abstract: | Dispersol dyes were photodegradated by solar-illuniinated catalysts. The effect of catalysttype, catalyst amount, PH, irradiation time, reaction medium and DO on decolorization efficiencywere discussed in detail.Dispersol dyes decolorized rapidly and decomposed to inorganic carbon finally. Thephotodegradation intermediates were analyzed with UV. IR and GC/MS, which showed that benzenering wns opened and alkylates were produced.Treatment of dispersol yellow-brown wastewater by solar-illuminated catalyst obtainedsatisfactory results: decolorized 86.7% and COD decreased 48.2%, which means that photocatalytictreatment of color wastewater is practical. |
