摘　　要：建立了1个气相色谱/串联质谱(GC/MS-MS)分析方法,对纺织品中卡拉花醛的含量进行测定。该方法以甲醇为萃取溶剂,超声萃取纺织品中的卡拉花醛,萃取温度为45℃,时间为30 min。萃取液经浓缩、定容、过滤后进行GC/MS-MS分析,采用外标法定量。该方法的定量下限为0. 10mg/kg,平均加标回收率为87. 45%～96. 86%,精密度(RSD)为2. 85%～9. 95%。该方法简便快速,灵敏度高,定量下限低,检测通量大,定量下限远远低于REACH法规的限量要求,可完全满足纺织品中卡拉花醛含量的日常检测工作需要。An effective method was established to determine the content of karanal in textiles by gas chromatography/tandem mass spectrometry (GC/MS-MS).Karanal in textiles was ultrasonically extracted at 45℃ for 30min,using methanol as the extraction solvent.The extract was then condensed and filtered,followed by the analysis of GC/MS-MS.The concentration of karanal was calibrated by the external standard method.The limit of quantification (LOQ)was 0.10mg/kg.The blank sample was spiked at three levels and the spiked average recoveries changed from 87.45% to 96.86%.The relative standard deviation changed from 2.85%to 9.95%.The proposed method was simple,accurate, sensitive,high detection throughput and convenient to operate.The limit of quantification (LOQ)was far less than the limited requirement of REACH regulation,and the proposed method could meet the demand completely on the routine analysis of karanal in textiles.
