Abstract

La/Fe/TiO 2 composite photocatalysts were synthesized by Sol-Gel method and well characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen-physical adsorption, and UV-Vis diffuse reflectance spectra (UV-Vis DRS). It is interesting that the doped catalysts were in anatase phase while the pure TiO 2 was in rutile phase. In addition, the composites possessed better physical chemical properties in photocatalytic activity than pure TiO 2 : stronger visible-light-response ability, larger specific surface area, and more regular shape in morphology. The photodegradation results of ammonia nitrogen indicate that: the La/Fe/TiO 2 had higher catalytic activity to ammonia nitrogen waste water compared pure TiO 2 and the other single metal-doped TiO 2 . pH 10 and 2 mmol/L H 2 O 2 were all beneficial to the removal of ammonia nitrogen by La/Fe/TiO 2 . However, the common inorganic ions of Cl − , NO 3 − , SO 4 2− , HCO 3 − /CO 3 2 − , Na + , K + , Ca 2+ and Mg 2+ in water all inhibited the degradation of ammonia nitrogen. By balance calculation, at least 20% of ammonia nitrogen was converted to N 2 during the 64.6% removal efficiency of ammonia nitrogen.
