An ultra performance liquid chromatography（UPLC）coupled with solid phase extraction（SPE） method was established for the determination of nine haloacetic acids（HAAs） in drinking water. The experimental conditions of UPLC and SPE were optimized. Three SPE cartridges with different sorbents were tested,and Lichrolut EN cartridges showed the best recoveries. A good baseline separation of target compounds were obtained in 6 minutes when using methanol and triethylamine phosphate buffer（pH 5.0） as mobile phase,triethylamine as ion pair reagent. The calibration curves of nine HAAs were linear in the certain concentration range with correlation coefficients of 0.995 7 -0.999 9. The limit of detection（LOD,S/N≥3） for monochloroacetic acid（MCAA） was 10.85 μg/L,and those for rest of target compounds were between 0.25 μg/L and 070 μg/L. Recoveries of HAAs at three spiked concentration levels ranged from 60% to 106% except for MCAA. The relative standard deviations（RSDs,n=5） of the method were between 2.0% and 5.7%. This method was applied in the determination of HAAs in tap water samples from a northern city in China,and five HAAs were detected.Therefore,the method was sensitive and convenient,and could be used in the trace determination of HAAs in drinking water.
