• Abstract: In accordance with the European commission's ecological standards for the control of acrylonitrile residues in acrylic fibers, a headspace solid-phase extraction and chromatography-mass spectrometry (hs-smpe-gc /MS) technique was used to establish a method for the determination of acrylonitrile residues in acrylic fibers. The detection limit of this method is less than 0.5 mg/kg, and the recovery is between 91.9 % and 97.7 %. 依照欧盟委员会关于生态标准对腈纶中丙烯腈残留量的控制，采用顶 空固相萃取和色质谱联用技术（HS-SMPE-GC/MS），建立了腈纶中丙烯腈残 留量的测定方法。该方法检测限低于 0.5 mg/kg，回收率在 91.9 % ～ 97.7 % 之间。
