The typical and emerging technique in preparation anic pollutants in environmental samples analysis were summarized. Headspace of VOCs in liquid and solid samples, passive sampling, SPE technique applied in extraction SVOCs from water samples, comparison of several popular extraction of SVOCs from soil, sediment and wastes, application of column chromatograph and gel permeation chromatograph were also introduced.
Key words: organic pollutants, preparation, extraction, clean-up, concentration
随着仪器技术的革命,越来越多的新型技术和分析仪器问世,如:高分辨色谱/高分辨质谱联用仪(HRCG/HRMS),超高效液相色谱/三重四级杆质谱(UPLC/TQ-MS),超高解析飞行时间质谱(UHD-TOF),毛细管电泳/质谱(CE/MS),高效液相色谱/四级杆质谱-飞行时间质谱联用仪(HPLC/Q-TOF),二维气相色谱(GC×GC),高场非对称波形离子迁移谱(FAIMS),加速器质谱(AMS)等等,检测灵敏度也不断提高,达到
