Abstract: The effectiveness of Cu(I) and Cu(II) Fenton's system to decolourize a wide range of structurally different synthetic dyes was investigated. The Cu(I)/peroxide system can effectively decolourize aridine orange, basic blue 17, bromo cresol purple, reactive blue 5, evans blue, Chicago sky blue, methyl orange, methyl red, neutral red, phenol red, reactive black 5, reactive brilliant violet and tropeolin 00 by more than 70% within 24 hours of incubation. Cu(II)/peroxide system can decolourize Chicago sky blue, reactive black 5, Remazol brilliant violet, poly R 478, reactive blue by more than 70% in 24 hours. Cu(II)/peroxide system was tested for its ability to decolourize industrial effluents and compared to other pyridine and succinic acid containing Cu(II) systems.
