Fe-natural zeolite as highly active heterogeneous catalyst in decolorization of reactive blue 4
MetadataShow full item record
Heterogeneous Fenton-like reaction using Fe-natural zeolite (Fe-NZ) was investigated for the decolorization of Reactive Blue 4(RB4). The effect of iron ions loading, H2O2 concentration and initial pH value were investigated. The maximum decolorization efficiency of 98.71% was achieved at 0.60 wt% of iron ions loading, 16 mM H2O2 concentration and at initial pH of 2.5. The high performance of Fe-NZ indicates that the heterogeneous Fenton-like could be efficiently employed for the treatment of wastewater containing azo dye.
