建立了两类阻燃剂中六种阻燃剂的分析方法。这些基团包括溴化阻燃剂(BFR)3，3‘，5，5’-四溴双酚A(TBBPA)、1，2，5，6，9，10-六溴环十二烷(HBCD)和四溴邻苯二甲酸酐(TBPA)以及三酯类有机磷阻燃剂(OPFR)三(2，3-二溴丙基)磷酸(TBPP)、乙基己基二苯基磷酸盐(EHDP)和三苯基磷酸酯(TPHP)。采用反相超高效液相色谱柱、不同的色谱柱、不同的流动相和梯度洗脱程序，在最短的时间内获得最佳分离效果。固相萃取(SPE)是从蒸馏水中进行预浓缩的一个步骤。然后在1-L空白地表水样品上进行了回收率最高的柱(Bond Elut ENV柱对所有化合物的回收率超过70%)的测试。将所建立的分析方法用于地表水样品中FRS的测定。在水样中发现的FRS浓度范围为0.03g(三苯基苯丙氨酸)至3.10gμg L−1(六氯环己烷)。方法检出限(MDL)为0.008~0.518μg/L−1，方法定量限(MQL)为0.023~1.555μg/L−1。
Analytical method for the determination of six flame retardants (FRs) from two groups was proposed. These groups included the brominated flame retardants (BFRs) 3,3′,5,5′-tetrabromobisphenol A (TBBPA), 1,2,5,6,9,10-hexabromocyclododecane (HBCD) and tetrabromophthalic anhydride (TBPA) and triester organophosphate flame retardants (OPFRs) tris(2,3-dibromopropyl) phosphate (TBPP), ethylhexyl diphenyl phosphate (EHDP) and triphenyl phosphate (TPhP). Reversed phase ultrahigh-performance liquid chromatography (UHPLC) with a UV detector, different chromatographic columns, different mobile phases and gradient elution programmes were used to obtain the best separations within the shortest possible time. Solid-phase extraction (SPE) was examined as a pre-concentration step from distilled water. The column with the highest recoveries (the Bond Elut ENV column gave recoveries over 70 % for all compounds) was then tested on 1-L blank surface water samples. The proposed analytical procedure was applied for the determination of FRs in surface water samples. The concentrations of FRs found in water samples ranged from 0.03 (TPhP) to 3.10 μg L−1 (HBCD). Method detection limits (MDLs) ranged from 0.008 to 0.518 μg L−1, and method quantification limits (MQLs) ranged from 0.023 to 1.555 μg L−1 for all compounds.
