| 摘 要： | 建立了玩具中三(2-氯乙基)磷酸酯、磷酸三邻甲苯酯、2,2′,4,4′,5-五溴联苯醚、2,2′,3,3′,4,4′,6,6′-八溴联苯醚等4种阻燃剂的气相色谱-质谱分析方法。玩具样品以V(正己烷):V(二氯甲烷)=1:1混合溶液为提取溶剂,超声提取30min,提取液以DB-5HT石英毛细管色谱柱(15m×0.25mm×0.10μm)分离后进行选择离子监测模式下的定性及定量分析。4种阻燃剂的定量限为0.1mg/kg,在低、中、高3个添加水平范围内,4种阻燃剂的平均回收率为93.5%～97.3%,相对标准偏差在2.4%～4.1%之间。

| Abstract: | An analytical method based on gas chromatography-mass spectrometry has been developed for the simultaneous determination of 4 flame retardants (tris (2-chloroethyl) phosphate, tri-o-cresyl phosphate, 2, 2', 4, 4', 5-pentabromodiphenyl ether and 2, 2', 3, 3', 4, 4', 6, 6'-octabromophenyl ether) in toys. Toy samples were extracted under ultrasonication for 30 min with n-hexane-dichloromethane (1∶1, V/V). The filtrate was injected into GC-MS and separated on a DB-5HT (15 m×0.25 mm×0.10 μm) chromatographic column. Qualitative and quantitative analysis was conducted under selected ion monitoring (SIM) mode. The limits of quantitation (LOQ) were 0.1 mg/kg for 4 flame retardants. The recoveries and relative standard deviations were 93.5%～97.3% and 2.4%～4.1%, respectively. |
