Abstract

In this study, a resin-supported Fe(III) catalyst (Fe/R) was developed for the degradation of Reactive Black 5 (RB5) by a heterogeneous Fenton-like reaction. The catalyst stability was evaluated by measuring color removal efficiency for five successive cycles. The Fe/R samples were characterized by XRD, TGA, SEM-EDS, and FTIR techniques as well as physical properties were determined using the BET method. The effect of major parameters including pH, H2O2 concentration, catalyst addition, initial dye concentration, reaction temperature, and amount of hydroxyl radical scavenger (tert-butyl alcohol) on the decolorization of RB5 was investigated. The results indicated that the RB5 decolorization rate increased with increasing H2O2 concentration, reaction temperature, and Fe/R addition, but decreased with increasing initial RB5 concentration, pH, and amount of hydroxyl radical scavenger. The total organic carbon (TOC) removal of RB5 was only 48.6%, and more H2O2 was required for TOC further removal.
