气提法富集气相色谱／质谱法测定水中痕量挥发有机物

Analysis of Trace Volatile Organic Compounds in Water by Gas Phase Stripping─GC/MS

摘要: 作者改进了气提法富集水中痕量挥发性有机物装置.研究了实验条件对水中痕量有机物富集的影响,并确定了最佳富集条件.以气提法富集气相色谱/质谱法(GC/MS)测定了水样中痕量挥发性有机物,取得了满意的结果.

Abstract: The device for gas phase stripping was stroved. The influence of opening condition on enrichment of volatile compounds in water was studied and the optimal conditions were selected. Water sample was determined by gas phase stripping-GC/MS,satisfactory results were obtained.
