中文摘要:
      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2.00μg/L~200μg/L范围内线性良好,方法检出限为1.01ng/L~2.85ng/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%。
英文摘要:
      A method was developed for determining 25 kinds of sulfonamides and quinolones in environmental water by solid phase extraction ultra performance liquid chromatography tandem mass spectrometry. By optimizing the experiment conditions, the method had good linearity in the range of 2.00μg/L~200μg/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%.
