Simultaneous determination of sulfonamides, fluoroquinolones, macrolides and trimethoprim in wastewater and river water by LC-tandem-MS
A sensitive and highly selective method for the simultaneous determination of sulfonamides, macrolides, fluoroquinolones and trimethoprim in wastewater and river water has been developed. Samples were enriched by solid-phase extraction and analysed by reversed-phase liquid chromatography coupled to electrospray ionization tandem mass spectrometry (LC-MS-MS). Several surrogate standards were used for quantification purposes. Absolute recoveries of individual antimicrobials were between 49 % and 133 % with RSD between 1 % and 18 % in all investigated matrices. Detection limits in low ng L-1 range were achieved. The method was successfully applied to the analysis of raw municipal wastewater, wastewater effluents and river waters.
