摘要
以丙酮为萃取溶剂,建立了超声萃取/气相色谱-串联质谱同时测定纺织品中6种禁用有机磷阻燃剂的分析方法。6种禁用有机磷阻燃剂三-(1-氮杂环丙基)氧化膦(TEPA)、三-(2-氯乙基)磷酸酯(TCEP)、三-(2,3-二氯丙基)磷酸酯(TDCP)、二-(2,3-二溴丙基)磷酸酯(DDBPP)、三-(邻甲苯基)磷酸酯(TOCP)和三-(2,3-二溴丙基)磷酸酯(TRIS)的线性范围分别为9.17～366.80、0.95～75.98、1.04～83.20、41.60～832.00、3.80～75.90、40.48～809.60μg/L,定量下限(S/N=10)分别为3.0、0.2、0.3、25.0、2.5、29.0μg/kg;方法的回收率为83%～96%,相对标准偏差为3.7%～9.8%。该方法简便快速、灵敏度高、定性准确,完全满足纺织品中禁用有机磷阻燃剂的检测要求。
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.
