A method was established for the determination of 8 diaryl phosphates (diphenyl phosphate,dibenzyl phosphate,bis(2-methylphenyl)hydrogen phosphate
&
bis(4-methylphenyl)hydrogen phosphate,bis(1-chloro-2-propyl)phosphate,bis(1,3-dichloro-2-propyl)phosphate,bis(2-chloroethyl)phosphate,bis(2,3-dibromopropyl)phosphate,bis(butoxyethyl)phosphate) in human urine using high performance liquid chromatography-tandem mass spectrometry. The target compounds were extracted,purified,concentrated and redissolved. Then,the target compounds were separated by a Kinetex C

(100 mm×2.1 mm,2.6 μm) column. 1 mmol/L ammonium acetate aqueous solution and methanol were used as mobile phase and gradient elution was adopted. Quantitative analysis was performed using isotope internal standard under ESI
-
ion source mode. Under optimal conditions,the target compounds showed good linearity with the correlation coefficients(
r

) greater than 0.99 within their respective ranges. The detection limits(LODs) were in the range of 0.05-0.30 μg/L,and the quantification limits(LOQs) were in the range of 0.2-1.0 μg/L. Average recoveries of the target compounds were in the range of 76.8%-115% at three different levels,and the relative standard deviations(RSDs) were between 2.3% and 9.8%. This method is simple,fast,highly sensitive and effective. It has been applied to analyze the levels of metabolites of organophosphate flame retardants in children’s urine in Longhua District,Shenzhen. It provides a scientific basis for the exposure assessment of metabolites of organophosphate flame retardants.
