| Abstract |
The aim of this work was to synthesize with and without Cu and Fe doping on manganese-based
octahedral molecular sieves (OMS-2) synthesized by the in-situ hydrothermal method and to test the reactive red 120 (RR120) degradation performance on Fenton-like reaction with peroxymonosulfate (PMS). The characterizations of catalysts were studied by X-ray diffraction (XRD), N2 adsorption-desorption, Field Emission
Scanning Electron Microscope (FESEM), X-ray absorption near edge structure (XANES) and X-ray
photoelectron spectroscopy (XPS) techniques. The effect of parameter such as catalyst loading, initial solution
pH and PMS concentration was examined by using design of experiment based on Box-Behnken design (BBD) on RR120 degradation in Fenton-like reaction. The OMS-2 and Cu-Fe-OMS-2 were completely synthesized via hydrothermal method confirmed by crystalline phase. The specific surface area of OMS-2 showed higher than
doped OMS-2. The morphologies of both catalysts were obvious in oval shape. The oxidation states of Cu and Fe
was measured by using XANES and XPS. The suitable condition of dye degradation was in pH 7.0, catalyst loading 0.4 g/L, and PMS concentration 3.536 mM for 50 ppm of initial RR120 concentration. The Cu-Fe-OMS2 showed higher activity in Fenton-like reaction than without doping. At reaction time 2 minute, the dye removal
at suitable condition was about 92% and 100% for without and with Cu-Fe, respectively. It can be concluded that Cu-Fe can enhance the Fenton-like reaction compared with OMS-2 alone. |
