| 中文摘要: |
| 采用超高效液相色谱-电喷雾二级质谱联用技术同时测定水中7种抗生素, 优化了试验条件。 磺胺甲恶唑、诺氟沙星、环丙沙星、氧氟沙星、四环素在 1.00 ng/L～1 000 ng/L 范围内线性良好, 定量下限为 1 ng/L, 土霉素、金霉素在10.0 ng/L～2 000 ng/L 范围内线性良好, 定量下限为10 ng/L, 去离子水和地表水样加标回收率为72.1% ～ 112% ,RSD 为0.6% ～ 9.2% 。 |
| 英文摘要: |
| An ultra performance liquid chromatography -electrospray ionization-tandem mass spectrometry (UPLC 2 ESI 2 MS/MS) analysis method wasestablished forthe simultaneousanalysisof 7 antibioticsin water. The experimentalconditionswereoptimizedto producefollowingresults: goodlinearityofsulfamethoxazole, norfloxacin, ciprofloxacin, ofloxacin and tetracyclinein the range from 1.00 ng/L to 1 000 ng/L and thelimitsof quantification(LOQ) 1 ng/L, the good linearity ofterramycin and aureomycin in the range from 10.0 ng/L to 2 000 ng/L and the LOQ 10 ng/L,the recoveriesofdeionized waterand surface waterfrom 72.1% to 112% , and the RSD from 0.6% to 9.2%. |
