摘　　要：采用浸渍法将钒酸铁通过硅烷偶联剂以共价键形式负载到棉织物上,制备得到Fe VO4负载型棉织物。通过傅里叶变换红外光谱(FTIR)、X射线衍射(XRD)和扫描电子显微镜(SEM)对产物进行表征。负载型催化剂的催化活性以其在可见光下对盐酸四环素的催化降解效果进行评价,并讨论了负载工艺对其催化活性的影响。结果表明,在可见光下,于最佳工艺(浴比1∶120,体系中乙醇与水体积比为1∶9,使用0.15 g Fe VO4,0.5%硅烷偶联剂,80℃负载9 h)制备得到的Fe VO4负载型棉织物,对盐酸四环素反应120 min后的降解率为97.63%。FeVO4-doped cotton fabric is prepared by forming covalent bond through dipping the FeVO4 suspension with silane coupling agent and is characterized by Fourier transform infrared spectroscopy （FTIR）, X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The catalytic activities are evaluated by the catalytic degradation towards tetracycline hydrochloride under visible light irradiation. The effect of loading conditions on the degradation of tetracycline hydrochloride is discussed. The results show that the degradation rate of FeVO4/cotton prepared with the optimal process [liquor ratio 1： 120, V（ethanol） ： V（water） 1：9, FeVO4 0,15 g, silane coupling agent 0,5%, reacting at 80 ℃ for 9 hi towards tetracycline hydrochloride is 97.63% after reacting for 120 min.
