Abstract Photo-Fenton reagent can degradate dye well. In the present paper, some main factors such as different light sources，the initial pH value，the dosage of Fe2+ and H2O2, the cation-exchange resin，etc.，which have great influences on degradation, were researched. Through numerous experiments，the optimum condition for dye direct fast light black G degradation was given. The results of the research were as follows：the sunlight can promote this reaction apparently，and the reaction time can greatly be shortened;Under optimal conditions，after the cation-exchange resin was introduced into the Fenton system, the activation of Fenton reagent for degradation reaction was enhanced to a great extent，the degradation effect of direct fast light black G was better，and the ratio of color removal was more than 94% within 40 min.
