碩士 === 國立高雄師範大學 === 化學系 === 99 === In this work,the microwave-enhance catalytic degradation (MECD) of phenol using the catalyst synthesized from precipitation of nickel-iron alloy with the magnetic was studied. Furthermore,nickel-iron oxides calcined under air at 300C, 400C and 500C (labeled as C300, C400 and C500,respectively).The characterization of catalysts were investigated by thermogravimetric analysis(TGA),powder X-ray diffraction (PXRD), fourier transform-infrared spectroscopy (FT-IR), temperature-programmed reduction (TPR),field-emission scanning electron microscope (FE-SEM),Transmission Electron Microscopy (TEM), and N2 adsorption / desorption isotherm(BET). Their catalytic activities towards the degradation of phenol on the efficiency of the degradation were further investigated under continous bubbling of air through the liquid phase and quantitatively evaluated by HPLC. Factors which might affect the efficiency of degradation such as initial concentration, temperature, pH and kinds of catalysts on the efficiency of the degradation were investigated. In MECD test, we have the better performance that under pH= 7 、40℃、0.18 g catalysts can totally degrades 100 mg/L phenol within 25 min.
