An effective method was established for the simultaneous determination of six kinds of banned organophosphorous flame retardants,including tris(1-aziridinyl) phosphine oxide(TEPA),tris(2-chloroethyl)phosphate(TCEP),tris(2,3-dichloropropyl)phosphate(TDCP),bis(2,3-dibromopropyl) phosphate(DDBPP),tri-o-tolyl phosphate(TOCP) and tris(2,3-dibromopropyl)phosphate(TRIS),in textiles by gas chromatography tandem mass spectrometry(GC-MS/MS) combined with ultrasonic extraction.The organophosphorous flame retardants in textiles were first ultrasonically extracted with acetone,and then analyzed by GC-MS/MS under multiple reaction monitoring (MRM) mode.The linear ranges of TEPA,TCEP,TDCP,DDBPP,TOCP and TRIS were 9.17-366.80,0.95-75.98,1.04-83.20,41.60-832.00,3.80-75.90,40.48-809.60 μg/L,respectively,and their quantitation limits(S/N=10)were 3.0,0.2,0.3,25.0,2.5,29.0 μg/kg,respectively.The spiked recoveries varied from 83% to 96% with RSDs of 3.7%-9.8%.The developed method was simple,rapid,sensitive and accurate,and could satisfy completely the demand of the analysis of banned organophosphorous flame retardants in textiles. |
