Photocatalytic degradation of Reactive Brilliant Blue KN-R by N,Fe- TiO2/FFA

摘要：

TiO2 photocatalyst modified by N and Fe ions was loaded on self-made fly ash forming adsorbent (FFA) using the sol-gel dip-coating process. The crystal structure and photoadsorption ability was characterized by X-ray diffraction (XRD) and UV-Vis spectrophotometer,respectively. The photo catalytic degradation of Reactive Brilliant Blue KN-R using N,Fe-TiCVFFA was examined. Effects of initial dye concentration,pH value and hydrogen peroxide dosage on degradation were studied. The degradation of the organic molecule followed a pseudo-first-order kinetics according to the Langmuir model. Under the optimum operation conditions,30 mg/L KN-R could be decolorized over 97.47% within 75 min.
