Abstract
The aims of this work were to synthesize manganese-based octahedral molecular sieves (K-OMS-2) prepared by the hydrothermal method without calcination process and to investigate the degradation performance of reactive red 120 (RR120) dye on Fenton-like reaction with peroxymonosulfate (PMS). The performances of dye degradation with initial concentration about 50 mg/L were designed by Box-behnken design (BBD) in effect of initial pH of solution, catalyst loading and initial concentration of peroxymonosulfate (PMS). The results were found that the crystalline phase of catalyst can be confirmed for K-OMS-2 material and the specific surface area was about 70.35 m2/g. The morphology of catalyst was obvious the aggregation of particles in oval shape with sizing about 1 µm. The oxidation states of catalyst were showed in Mn3+ and Mn4+ with mass ratio at about 0.28. The results of degradation performance of reactive red 120 (RR120) dye was found that the three effects were significant on degradation efficiency of dye. The optimal condition was in pH 6.67, catalyst loading 1.78 g/L and initial PMS concentration 4.53 mM at reaction time 2 mins, in which the dye removal was about 98%. This research showed that K-OMS-2 can be used for Fenton-like reaction in neutral pH condition.
