固相微萃取—毛细管气相色谱法快速分析水中酚类化合物

Fast analysis of phenol by solid phase micro extraction/ capillary GC

固相微萃取是一种快速、简便、集萃取浓缩进样于一体的样品前处理技术 ,具有分析时间短、灵敏度高、无需有机溶剂的优点。本工作用固相微萃取富集水中酚类化合物 ,毛细管气相色谱分离分析 ,整个分析过程只需 45 min,检出限可达 1 .0～ 1 0 .0 μg/ L,已用于地面水、海水、工厂废水中酚类化合物含量的测定。

Solid Phase Microextration(SPME), a fast, simple, practical and solventless sample extraction teniques,greatly reduces analysis time and improves minimum detection limits Phenol in water were analyzed by using SPME Capillary GC FID The whole procedure is just 45mininus, and the minimum detection limits reach 1 0~10 0μg/L It has been applied to the determination of Phenol in surface water and waste water
