摘　　要：以Bi(NO_(3))_(3)·5H_(2)O和Na_(2)WO_(4)·5H_(2)O为原料,采用水热法制备了花球状Bi_(2)WO_(6)光催化剂。利用XRD和SEM对其进行了晶态结构和微观形貌表征。以环丙沙星为目标污染物,研究了光催化剂对污染物的光催化降解效率。用可见光照射2h,催化剂样品BWO-12对环丙沙星的降解效率为84.2%。制备的光催化剂在医药废水的处理中具有很好的应用前景。Applied Bi(NO_(3))_(3)·5H_(2)O and Na_(2)WO_(4)·5H_(2)O as raw materials,flower shaped Bi_(2)WO_(6) photocatalysts were prepared by hydrothermal method.XRD and SEM were used to characterize the crystal structure and micro morphology of samples.Applied ciprofloxacin as the target pollutant,the photocatalytic degradation efficiency of photocatalysts on pollutants was studied.Illuminate with visible light for 2 h,the degradation efficiency of ciprofloxacin by catalyst sample BWO-12 was 84.2%.The obtained photocatalyst had good application prospects in medical wastewater treatment.
