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。
