| 中文摘要: |
| 采用固相萃取高效液相色谱串联质谱法(SPE-HPLC-MS/MS)快速测定水中23种抗生素。通过试验优化测定条件,使方法在1.00 μg/L~100 μg/L范围内线性良好,方法检出限为0.05 ng/L~0.20 ng/L,地表水样品加标回收率为65.2%~121%,测定结果的RSD为1.2%~13%。将该方法用于8座污水处理厂周边水域实际样品测定,结果7种抗生素检出,测定值为3.5 ng/L~81.6 ng/L。 |
| 英文摘要: |
| An analytical method based on solid phase extraction coupled with high performance liquid chromatography tandem mass spectrometry (SPE HPLC MS/MS) was used for the rapid determination of 23 antibiotics in water.Through optimizing the determination conditions, the method exhibited good linearity over the range of 100 μg/L~1 00 μg/L,and the method detection limits were from 0.05 ng/L to 020 ng/L. The spiked recovery rates of surface water samples ranged from 652% to 121%, and the RSDs of the measurement results ranged from 12% to 13%.The method was applied to actual water samples from areas surrounding eight sewage treatment plants, and seven antibiotics were detected at concentrations ranging from 35 ng/L~816 ng/L. |
