摘　　要：通过气质联用法对纺织品中两种阻燃剂(二溴新戊二醇,三溴新戊醇)和一种阻燃剂中间体(2,3-二溴丙醇)进行检测。优化了超声前处理萃取溶剂、萃取时间以及色谱-质谱条件。对纺织品中常用的棉、苎麻、羊毛、粘纤贴衬布样品进行加标试验,发现两种新型阻燃剂和一种阻燃剂中间体的回收率在80.2%~93.4%,相对标准偏差在4.1%~7.6%,线性范围为0.5~10.0 mg/L,定量限为1.0 mg/kg。该方法前处理过程简单,线性范围广,回收率高,适用于纺织品中两种新型阻燃剂和一种阻燃剂中间体的同时检测。Two flame retardants(dibromoneopentyl glycol,tribromoneopentyl alcohol)and one flame retardant in⁃termediate(2,3-dibromopropanol)in textiles are detected by GC-MS.The extraction solvent,extraction time of ultrasonic pretreatment and chromatographic-mass spectrometry conditions are optimized.A standard addition experiment is carried out on cotton,linen,silk,acrylic fabric samples which commonly used in textiles.In addi⁃tion,the recoveries and relative standard deviations of the two new flame retardants and one flame retardant in⁃termediate are in the range of 80.2%-93.4%and 4.1%-7.6%,the linear range is 0.5-10.0 mg/L,and the limit of quantification is 1.0 mg/kg.Due to the simple pretreatment process,wide linear range and high recovery rate,the method is suitable for the simultaneous detection of two novel flame retardants and one intermediate in textiles.
