ABSTRACT
ObjectiveA method was developed for the rapid determination of 18 common disinfection by-products including halogenated oxides and haloacetic acid (HAAs) in drinking water by high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). MethodThe water sample was filtered by 0.22 μm hydrophilic membrane then the analytes were separated on a PFP (2.1 mm× 100 mm, 2.7 μm) 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 (MRM) 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 1, 10 and20 times of LOQ of each analyte were 91.6%‒101.8%, and the relative standard deviation (RSD) was 1.2%‒6.4%. The LOD and LOQ were 0.020‒2 μg·L-1 and 0.050‒5 μg·L-1, respectively. ConclusionThis method is simple, sensitive and accurate, and could be used for the routine analysis of 18 common disinfection by-products in drinking water.
