摘　　要：通过气质联用法对纺织品中双(2-乙基己基)四溴邻苯二甲酸酯进行了检测研究。超声前处理的萃取溶剂、萃取时间以及色谱-质谱试验条件对双(2-乙基己基)四溴邻苯二甲酸酯的检测具有重大影响。对纺织品中常用的棉、羊毛和涤纶贴衬布样品进行了加标试验,双(2-乙基己基)四溴邻苯二甲酸酯的回收率在83.7%~103.3%的范围内,相对标准偏差在4.0%~9.4%范围,线性范围为1.0 mg/L~10.0 mg/L,定量限为20.0 mg/kg。该方法前处理过程简单,不需要旋蒸过程;采用内标方法测定,定量准确可靠;该方法回收率高,相对标准偏差小,适用于纺织品中双(2-乙基己基)四溴邻苯二甲酸酯的检测。The determination of bis(2-ethylhexyl)tetrabromophthalate in textiles was studied by GC-MS.The extraction solvent,extraction time of ultrasonic pretreatment and GC-MS experimental conditions have great influence on the detection of bis(2-ethyl-hexyl)tetrabromophthalate.The spiking experiment was carried out on cotton,wool and polyester interlining samples that common-ly used in textiles.The recovery of bis(2-ethylhexyl)tetrabromophthalate was in the range of 83.7%~103.3%,the relative standard deviation was in the range of 4.0%-9.4%.In addition,the linear range and the quantitative limit of bis(2-ethylhexyl)tetrabromoph-thalate was 1.0 mg/L~10.0 mg/L and 20.0 mg/kg,respectively.The method with simple pretreatment process and does not need ro-tating evaporation step;the internal standard method which used here make it accurately and reliably;due to the high recovery and small relative standard deviation,this method is fit for detecting bis(2-ethylhexyl)tetrabromophthalate in textiles.
