建立了一种分析室内粉尘中有机磷阻燃剂(OPFR)的新的高效分析方法。该方法包括超声和涡流萃取步骤，然后用Florisil固相萃取柱净化萃取物，并用气相色谱-质谱仪(GC-MS)分析纯化后的萃取物。方法回收率在76%~127%之间。除了挥发性的OPFR，如磷酸三乙酯(TEP)和磷酸三(正丙基)酯(TNPP)，它们在蒸发步骤中部分丢失。添加粉尘样品的日间精密度为
A new and efficient analytical method was developed and validated for the analysis of organophosphorus flame retardants (OPFRs) in indoor dust samples. This method involves an extraction step by ultrasonication and vortex, followed by extract clean-up with Florisil solid-phase extraction cartridges and analysis of the purified extracts by gas chromatography-mass spectrometry (GC-MS). Method recoveries ranged between 76 and 127%. except for volatile OPFRs, such as triethyl phosphate (TEP) and tri-(n-propyl) phosphate (TnPP), which were partially lost during evaporation steps. The between day precision on spiked dust samples was
