超声萃取／快速溶剂萃取．气质联用测定烟用拉线中邻苯二甲酸酯类物质

Determination of Phthalates in Tear Tapes for Cigarette Packaging Using Ultrasonic Extraction /ASE Method Coupling with GC-MS

建立了采用气相色谱．质谱联用法（GC．MS）同时检测10种邻苯二甲酸酯类物质的方法，并用此方法测出了5种烟用拉线中含有的2种邻苯二甲酸酯类物质DEHP和DIBP的含量。以正己烷为提取溶剂，分别采用超声提取法和ASE快速溶剂萃取法对烟用拉线进行了萃取。结果表明，超声提取的回收率在78．3％～91．7％之间，RSD在7．95％～9．82％之间，ASE萃取技术的回收率在82．2％-93．8％之间，RSD在4．95％-7．87％之间；ASE萃取技术有较高的回收率和精密度，适宜用于烟用拉线检测前的处理过程。

A GC-MS method for simultaneous detection of 10 kinds of phthalates was developed. DEHP and DIBP were detected in 5 kinds of tear tapes for cigarette packaging, and the contents were determined using the method. The phthalates was extracted with hexane by ultrasonically assisted procedure and ASE method respectively. The recoveries of the phthalates are between 70.8% - 91.7% with relative standard deviations of 7.95% - 9.82% when dealing with the ultrasonically assisted procedure, and between 82.2% -93.8% % with relative standard deviations of 4.95% - 7.87% by the ASE procedure. It was concluded that the ASE procedure is the better pretreatment of tear tape for cigarette packaging.
