摘 要:建立了气相色谱-串联质谱(GC-MS/MS)法同时测定纺织品中苯乙酮、邻苯二甲酸酯类和己二酸酯类等21种塑化剂的方法。样品经四氢呋喃超声提取,正己烷沉淀净化后,采用GC-MS/MS多反应监测(MRM)模式测定,外标法定量。21种目标物在线性范围内呈现良好的线性关系,且相关系数不小于0.9912,检出限为0.06~0.49 mg/kg,加标回收率为87.1%~105.4%,相对标准偏差为3.1%~9.3%。该方法简单、快速、可靠,适用于纺织品中多种塑化剂的快速筛查、确证和定量测定。A high throughput method based on gas chromatography-tandem mass spectrometry(GC-MS/MS) was established for the determination of 21 kinds of acetophenone, phthalate esters and adipates compounds in textiles. The samples were ultrasonically extracted with tetrahydrofuran,and then precipitated by adding hexane. All the samples were detected in selected reaction monitoring(SRM) mode. The correlation coefficients for 21 compounds were not less than 0.9912,and the method detection limits were in the range of 0.06-0.49 mg/kg. The average recoveries ranged from 87.1% to 105.4% with the RSDs of 3.1%-9.3%. The method was simple,rapid and reliable. It is suitable for the rapid screening,identification and quantification of plasticizers in textiles.
