摘要
本文建立了采用甲醇超声波萃取，低温真空浓缩定容，C18固相萃取小柱净化，氮吹定容，最后采用气相色谱-质谱法（GC／MS）对橡胶鞋底材料中12种N-亚硝基胺化合物进行定性定量的检测方法，同时考查了方法的检测限、回收率和精密度。
The determination method of 12 N-introsamines in rubber sole materials was developed.The samples were extracted by ultrasonic treatment with methanol as solvent,and low temperature and vacuum concentration,then determined by Gas chromatography-mass spectrometry after purifying by C18 solid-phase extraction cartridge.The limit of determination ,the recobery rate and the relative standard deviation were determined.
