摘要：

This study aimed at comparing various advanced oxidation processes (H2O2, UV, UV/H2O2, Fe2+/H2O2, UV/Fe2+/H2O2) for textile dye Reactive Red 195 decolorization. The use of blast furnace dust (BFD) was also investigated as an alternative source of iron in catalytic peroxidation with and without UV radiation. The effects of H2O2 and dye concentrations in kinetics of decolorization were studied. Decolorization reactions follow pseudo-first order kinetics. The results indicated greater efficiency of decolorization in the photo-Fenton system with the use of BFD; however, the use of BFD in the Fenton system without irradiation reached the same efficiency with a reaction time only 15 minutes superior. The use of blast furnace dust increased considerably the rates of reactions and is very promising as a source of iron.
