| 摘 要： | 采用固相萃取技术(solid phase extraction,SPE )对饮用水体样品中的7类30种抗生素药物残留(包括青霉素类1种、林可胺类1种、氯霉素类3种、喹诺酮类3种、四环素类4种、大环内酯类5种、磺胺类抗生素13种)进行富集,使用液相色谱/串联质谱仪(LC-MS/MS)的多反应监测模式(multiple reaction monitor,MRM)进行定性定量分析.该方法的平均回收率为61.89%～152.66%,相对标准偏差为1.60%～14.97%,方法最低检出浓度为1.5 ng/L,表明该方法完全适用于饮用水体中杭生素残留的监测分析. |

| Abstract: | 30 kinds of antibodies(1 kind of penicillins,1 kind of lincomycins,3 kinds of chloramphenicols,3 kinds of quinolones,4 kinds of tetracyclines,5 kinds of macrolides and 13 kinds of sulfonamides) in tap water samples were enriched using solid phase extraction and analyzed qualitatively and quantitatively using LC-MS/MS in multiple reaction monitor mode.The average recovery rate is 61.89% to 152.66%,the RSD is 1.60% to 14.97%,and the MLD is 1.5 ng/L.All the data show that this method can be used to analyze res... |
