摘　　要：建立了气相色谱-质谱联用法同时测定纺织品中10种邻苯二甲酸酯含量的快速方法。采用适宜的色谱条件对目标产物进行分离,一次进样分离只需23 min。此外,还探究了不同萃取溶剂、萃取方法以及超声萃取溶剂的温度和时间对测定结果的影响。在该方法的色谱条件下,通过测定回收率和目标产物的线性来验证方法的可行性。实验结果表明,6种邻苯二甲酸酯(DIBP、DBP、DPP、BPP、DEHP和DNOP)在0.4~10 mg/L范围内线性良好,加标回收率在85.5%~101.0%范围内,4种邻苯二甲酸酯(DMEP、DIHP、DINP和DIDP)在2~50 mg/L范围内线性良好,加标回收率在92.7%~102.1%范围内,满足ISO 14389-2014的标准要求。This paper established a rapid method for simultaneous determination of 10 phthalates residues in textiles by gas chromatography-mass spectrometry.Through suitable chromatographic conditions,the target products was separated,only need 23 minutes.Besides,this paper also explored the effects of different extraction solvents,extraction methods,ultrasonic extraction solvent temperature and temperature on determinating the results.The feasibility of the method was verified by the recovery rate test under this chromatographic conditions.Experiment results showed that 6 phthalates residues(DIBP,DBP,DPP,BPP,DEHP and DNOP)had good linearity in the range of 0.5 mg/L^20 mg/L and the recovery was in the range of 85.5%~101.0%,4 phthalates residues(DMEP,DIHP,DINP and DIDP)had good linearity in the range of 2 mg/L^50 mg/L and the recovery was in the range of 92.7%~102.1%,which met the requirement of ISO 14389-2014.
