摘　　要：采用溶胶-凝胶法,制备了纳米Fe3+/TiO2薄膜,利用XRD、TEM等测试手段进行了样品的表征分析,以降解含阿奇霉素废水为反应模型,研究了纳米Fe3+/TiO2薄膜的紫外光照射催化活性及薄膜的重复使用效果。结果表明,纳米Fe3+/TiO2薄膜不易失活,其催化活性寿命较粉体纳米Fe3+/TiO2的强,且再生性能好,薄膜重复使用4次,仍有明显的降解效果。Nanometer Fe^3＋/TiO2 film was prepared by sol-gel method, the surface morphology of samples was characterized by XRD and TEM, the UV photocatalytic activity was measured by degradation using photocatalyti tigation. The particle Fe^3＋/TiO2, and the films have good regeneration property, degradation efficiency of film was high after reusing four times.
