摘　　要：以TiOSO4为原料,用水热法制备了掺铁TiO2晶体粉末,用XRD测定了样品的晶型,研究了以自制的催化剂对碱性品红溶液的光催化降解行为。实验结果表明:自制的掺铁TiO2为锐钛矿型TiO2(即A-TiO2);光催化降解碱性品红溶液的优化条件是:2 mg/L的碱性品红溶液、掺铁量5%(摩尔分数)、A-TiO2粉末加入量1.2 g/L,室温搅拌下紫外(λ=365 nm)光照降解反应3 h,此条件下碱性品红溶液降解率达到88.59%。With TiOSO4 as raw materials, iron-doped TiO2 was prepared by hydrothermal method and detected by XRD to characterize its crystal structure. The photo-eatalystic degeneration of fuchsin by this catalyst under UV-light was studied. Results show that the crystal structure of as-prepared iron-doped TiO2 is anatase-TiO2 （ namely, A-TiO2 ）. With 2 mg/L fuehsin, 5% Fe doping （mole fraction） and a dosage of catalyst A-TiO2 as 1.2 g/L, after being stirred at room temperature, the degeneration rate can be up to 88.59% for fuchsin illuminated by UV-light （365 nm） for 3 h.
