Abstract： In this experiment，a methodforthedeterminationof tris （xylene）phosphate in water bygas chromatography-mass spectrometry was established.The test was carried out by liquid-liquid extraction method， 60mL dichloromethane was used to extracttwice，after merging，thecontentof tris （xylene）phosphate was determined by internal standard method.The results showed that the detection limit of the method was 0.07μg/L ，thelower limit of determination was 0.28μg/L ，the standard curve had good linearity，the relative standard deviationwas 5.35%-10.01% ， and the recovery rate was . The method is simple，rapid and accurate，and can meet the test requirements of tris（dimethylphenyl） phosphate in water quality.
