采用固相萃取-超高效液相色谱串联质谱法测定环境水样中25种磺胺类和喹诺酮类抗生素,通过优化试验条件,使方法在2.00 µg/L~200 µg/L范围内线性良好,方法检出限为1.01 ng/L~2.85 ng/L,7次测定结果的RSD为2.3%~8.0%.将该方法用于自来水和地表水测定,结果均为未检出,高、低质量浓度水平的加标回收率为61.2%~102%.
Determination of Antibiotics in Environmental Water by Solid Phase Extraction-UPLC-MS/MS
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%.
