| Abstract: |
| The impregnated method was used to prepare the catalyst Fe/zeolite by using FeSO4 solution as dipping agent. The property and mechanish of oxidizing dye reactive black 5 by catalyst Fe/zeolite under the presence of H2O2 was studied. The results showed that the Fe modified zeolite is superior to zeolite for degradating reactive black 5. The optimum preparation conditions was that the concentration of FeSO4 solution 0.1 mol/L, impregnating time 12 h, calcination temperature 450℃, calcination time 3 h. When reaction time 60 min, reaction temperature 30℃, dye wastewater pH 3, H2O2 concentration 200 mg/L and catalyst dosage 1.5 g/L, the degradation efficiency of reactive black 5 could reach 98.9 %. It is found that ?OH plays the major role of degradating dye reactive black 5 by the catalyst Fe/zeolite. |
