摘　　要：通过简易水热法—微波法制备了Cu掺杂TiO_(2)催化剂复合光催化材料(Cu-TiO_(2)),利用扫描电子显微镜(SEM)研究Cu-TiO_(2)光催化剂微观形貌,同时考察环丙沙星(CIP)废水初始浓度、初始p H值、Cu掺杂量和催化剂投加量对光催化降解CIP废水效率的影响。结果表明,所制备的Cu-TiO_(2)催化剂具有形貌均匀,为球形结构,直径为10μm。当CIP初始浓度为20 mg/L、初始pH为7、Cu掺杂量为3%时、催化剂投加量为30 mg/L,可见光照射120 min时,Cu-TiO_(2)对CIP的降解效率约为95.7%。The Cu-doped TiO_(2) catalyst composite photocatalytic material(Cu-TiO_(2))was prepared by a simple hydrothermal-microwave method,and the microscopic morphology of Cu-TiO_(2) photocatalyst was studied by scanning electron microscopy(SEM).The initial concentration of ciprofloxacin(CIP)wastewater,initial pH,Cu doping and catalyst dosage on the efficiency of photocatalytic degradation of CIP wastewater were investigated.The results showed that the prepared Cu-TiO_(2) catalysts had uniform morphology and spherical structure with a diameter of 10μm.The degradation efficiency of Cu-TiO_(2) on CIP was about 95.7%when the initial concentration of CIP was 20 mg/L,the initial pH was 7,the Cu doping amount was 3%,the catalyst dosage was 30 mg/L and the visible light irradiation time was 120 min.
