Comparison of three advanced oxidation processes for degradation of textile dyes

摘要: This paper examines the use of three advanced oxidation processes in degrading textile dye, Reactive Red 235. The dye was oxidised using ozonation, standard Fenton's reagent (Fe2+/H2O2) and a modified photo-Fenton's process (UV/Fe oxalate/H2O2) under variety conditions. effects initial concentration, pH NaCl concentration were studied for each process. Each found to have different optimum conditions as determined by underlying reaction mechanisms.
