气质联用法同时测定纺织品中17种邻苯二甲酸酯类增塑剂

Determination of 17 Phthalates in Textiles by Gas Chromatography-Mass Spectrometry

建立了气质联用法测定纺织品中17种邻苯二甲酸酯的分析方法,以四氢呋喃为萃取溶剂,采用超声萃取法提取纺织品中的17种邻苯二甲酸酯,优化了样品萃取溶剂的选择和仪器分析条件。结果表明:本方法17种邻苯二甲酸酯的检出限在7.2~66.1 mg/kg之间,加标回收率为90.5%~99.7%,相对标准偏差为2.8%~7.8%。本方法仪器分析时间短,回收率高,重复性好,结果可靠,适用于纺织品中17种邻苯二甲酸酯的检测。

An analytical method for the determination of 17 Phthalate in textiles by GC-MS was established.THF was used as the extraction solvent and ultrasonic extraction was used to extract 17 Phthalates in textiles,optimized the sample extraction solvent conditions and instrument analysis conditions.The results showed that the detection limits of 17 Phthalates were 7.2-66.1 mg/kg,the recoveries range from 90.5%-99.7%,and the relative standard deviation is at the range of 2.8%-7.8%.The method has short analytical time,high recovery,good repeatability and reliable results,and is suitable for the detection of 17 Phthalates in textiles.
