| Abstract: | An ultra-high performance liquid chromatography -electrospray ionization tandem mass spectrometry （ UPLC-ESI-MS/MS） method was developed for the simultaneous determination of 32 drugs in water body .Firstly, the water sample was a-cidized to pH 2.0 by dilute sulphuric acid, and its volume was 500 mL;then the sample was richened and purified through solid -phase extraction with an Oasis HLB column;finally it was detected by using UPLC -ESI-MS/MS method.The ESI-MS/MS de-tection was achieved through the simultaneous scanning of ESI positive and negative ions , multiple reaction monitoring （ MRM） for data collection , and external standard method for quantitative analysis .The average standard -adding recovery of various drugs was 61.4%~116.0%, the RSD varied from 0.7%to 17.3%, and their detection limit was 0.4~2.9 ng/L. |
