Simultaneous determination of 18 common disinfection by-product residues in drinking water by high performance liquid chromatography-tandem mass spectrometry
Journal Title: Shanghai Journal of Preventive Medicine - Year 2023, Vol 35, Issue 7
Abstract
ObjectiveA method was developed for the rapid determination of 18 common disinfection by-products including halogenated oxides and haloacetic acid ï¼HAAsï¼ in drinking water by high performance liquid chromatography tandem mass spectrometry ï¼HPLC-MS/MSï¼.MethodThe water sample was filtered by 0.22 μm hydrophilic membrane then the analytes were separated on a PFP ï¼2.1 mmà 100 mmï¼ 2.7 μmï¼ pentafluorophenyl column with 0.1% acetic acid and acetonitrile as mobile phase gradient elution. Ionization in anionic electrospray mode was detected by multi-reaction monitoring ï¼MRMï¼ mode. The external standard method was used for quantitation.ResultsThe correlation coefficients of 18 disinfection by-products were above 0.999 in the corresponding linear range. The average spiked recoveries of 1ï¼ 10 and 20 times of LOQ of each analyte were 91.6%â101.8%ï¼ and the relative standard deviation ï¼RSDï¼ was 1.2%â6.4%. The LOD and LOQ were 0.020â2 μg·L-1 and 0.050â5 μg·L-1ï¼ respectively.ConclusionThis method is simpleï¼ sensitive and accurateï¼ and could be used for the routine analysis of 18 common disinfection by-products in drinking water.
