吹扫捕集-气相色谱/质谱法测定纺织品中挥发性氯代苯

Determination of Volatile Chlorbenzenes in Textile by Purge & Trap-gas Chromatography/mass Spectrometry (GC/MS)

本文采用吹扫捕集进样-气相色谱/质谱法测定了纺织品中1-氯代苯、1,2-二氯代苯、1,4-二氯代苯等三种具有挥发性的氯代苯类化合物。实验优化了仪器条件,及吹扫捕集时间。实验获得3种氯代苯化合物的添加回收率在90-97%之间。该方法具有稳定性好、灵敏度高,且不需要消耗有机溶剂等特点,可简单、快速的测定纺织品中挥发性较强的氯代苯类化合物。

In this paper,three kind of volatile chlorbenzenes in textile were determined by gas chromatography/mass spectrometry（GC/MS） using the purge and trap sampler.The instrument conditions and the purge and trap time were optimized.The average recoveries of these chlorbenzenes were ranged from 90% to 97%.This method was simple and accurate determination of volatile chlorbenzenes in textile.This method also needs not consume the organic solvent,and the stability and sensibility can meet the analysis.
