氯酚是氯取代苯酚类化合物的总称,其中2,4-二氯酚、2,4,6-三氯酚和五氯酚被许多国家列为优先控制的污染物.随着对氯酚监测研究的逐步深入,各种新型的痕量富集净化和检测技术不断涌现。本文主要综述了氯酚的液液萃取、液相微萃取、固相萃取、固相微萃取、搅拌棒吸附萃取、索氏提取、加速溶剂萃取和QuEChERS等样品前处理新技术及气/质联用、液/质联用和毛细管电泳等分析新方法,并对氯酚微量检测的发展趋势进行了展望。
Chlorophenols are the general term for chlorinated phenolic compounds, of which 2,4-dichlorophenol, 2,4,6-trichlorophenol and pentachlorophenol are listed as priority pollutants in many countries. With the monitoring of parachlorophenols With the deepening of research, a variety of new trace enrichment and detection technologies are emerging. In this paper, the new technologies of liquid-liquid extraction, liquid-phase microextraction, solid-phase extraction, solid-phase microextraction, stir bar adsorption extraction, Soxhlet extraction, accelerated solvent extraction and QuEChERS pretreatment and gas / The new method was analyzed by liquid / mass spectrometry and capillary electrophoresis, and the development trend of trace detection of chlorophenol was prospected.
