摘　　要：以硫酸钛为原料用水热法制备了掺Fe3+TiO2粉末,用SEM测定了样品的形貌和晶型,研究了以自制的掺Fe3+A-TiO2对碱性品红溶液的光催化降解作用。结果表明:所制备的TiO2为锐钛矿型TiO2(A-TiO2)。可见光照射下,用自制的掺Fe3+A-TiO2降解碱性品红溶液的最佳条件是:2mg.L-1的碱性品红溶液中加入0.0600g掺5%Fe3+(摩尔比)A-TiO2粉末,室温下恒温反应3h,降解率达到80.37%。Fe^3＋-doped TiO2 powders were prepared by hydrothermal method with titanium sulfate as raw materials,that were characterized by SEM,and the photocatalytic degeneration of home-made Fe^3＋-doped A-TiO2 on basic fuchsin was studied.The home-made TiO2 was anatase TiO2（A-TiO2）.The highest degeneration rate for basic fuchsin was 80.37% under follow optimum conditions：adding quality of 0.0600g for home-made Fe^3＋-doped A-TiO2 powders with mole ratio of 5% into the basic fuchsin solution concentration of 2mg·L-1 reacted under visible light for 3h at constant room temperature.
