摘要

Fenton reagent was employed to treat and decolorize the wastewater of Reactive Red SBE by on-line spectrophotometry. The effects of initial FeSO₄ concentration, initial H₂O₂ concentration, pH, reactive red SBE and temperature on the decoloration of reactive red SBE were investigated. The results show that Fenton oxidize process follows pseudo first order kinetics in the first stage and reaction activation energy is 2.608 kJ/mol. The decolorizing reaction rate constants (k) increase with the rise of FeSO₄ concentration, H₂O₂ concentration, temperature, but decrease with the rise of reactive red SBE, and the optimum pH is 3. Initial FeSO₄ concentration and initial H₂O₂ concentration against k are linear correlation.
