| 摘要: |
| 环境中残留的氟喹诺酮类物质(FQs)对人体健康构成威胁,自来水厂对阻断FQs进入饮用水中具有关键作用．选取长江、太湖、大溪水库和松花江水源水及江苏省A、B和C水厂的工艺出水探索同时检测诺氟沙星、环丙沙星、恩诺沙星和氧氟沙星的方法,并分析FQs在水处理工艺流程中的迁移规律．结果表明,长江水中FQs的质量浓度在51~129 ng／L,太湖水中65~204 ng／L,大溪水库中62~248 ng／L,松花江水中61~165 ng／L．水处理工艺出水FQs残留结果表明,常规水处理工艺对FQs的去除率在20％~40％,起主导作用的是混凝沉淀过程,采用臭氧-活性炭工艺去除率可达20％~60％． |

| Abstract: |
| An investigation was performed for the simultaneous determination of norfloxacin (NOR), ciprofloxacin (CIP), enrofloxacin (ENR), and ofloxacin (OFL). The developed method was successfully applied to analyze the fate of Fluoroquinolones (FQs) in water treatment processes. Four FQs were found in Yangtze River, Taihu Lake, Dasi Reservoir, Songhua River, and drinking water treatment processes of A,B and C in Jiangsu. Analyses of samples from Yangtze River, Taihu Lake, Dasi Reservoir and Songhua River indicated that FQs were present at concentrations of 51-9,5-4,2-248 and 61-165 ng／L, respectively. FQs residues in water treatment processes show that the removal efficiency of conventional water treatment processes is between 20％ and 40％, and the coagulation-sedimentation process plays a dominant role. The removal efficiency of ozone-activated carbon process is about 20％-60％. |
