A method was developed for determining 25 kinds of sulfonamides and quinolones in environmen-tal water by solid phase extraction-ultra performance liquid chromatography-tandem mass spectrometry.By opti-mizing the experiment conditions,the method had good linearity in the range of 2.00 µg/L~200 pg/L.The method detection limits ranged from 1.01 ng/L to 2.85 ng/L,and the RSDs of 7 measurements ranged from 2.3%to 8.0%.The method was applied in determining tap water and surface water,and the results were not detected.The spiked recoveries with high and low mass concentration levels were 61.2%~102%.
