英文摘要	A method for the determination of five representative organic UV filters ethylhexyl methoxycinnamate ( EHMC ) , benzophenone-3 ( BP-3 ) , 4-methylbenzylidene camphor ( 4-MBC) , octocrylene ( OC ) , homosalate ( HMS) in water was investigated. The method was based on derivatization , solid phase extraction ( SPE) , followed by determination with gas chromatography-mass spectrometry ( GC-MS ). The variables involved in the derivatization of BP-3 and HMS were optimized, and SPE conditions were studied. For derivatization, 100 N, O-bis ( trimethylsilyl) trifluoroacetamide ( BSTFA ) was used as derivatization reagent and reacted with BP-3 and HMS at 100 t for 100 min. For SPE, the pH value of water sample was adjusted to 3-5. The Oasis HLB cartridges were employed and the solution of ethyl acetate and dichloromethane ( 1 :1, v/v) was used as the eluting solvent, and good recoveries of the target compounds were obtained. The limits of detection ( LODs ) and the limits of quantification ( LOQs) for the five target compounds in water samples were 0. 5-1. 2 ng/L and 1. 4-4. 0 ng/L, respectively. The recoveries of spiked water samples were 87. 85% -102. 34% with good repeatability and reproducibility ( RSD<5% , n = 3) for all the target compounds. Finally, the validated method was applied to analysis the representative IN filters in water samples collected from a wastewater treatment plant in Kunming city of Yunnan province.
