| 摘 要： | 由于多氯联苯(PCBs)在环境样品中残留浓度低,基质复杂干扰多,必须对环境样品进行预处理,并且结合先进的分析测试方法进行分析。文章综述了PCBs的性质及其主要来源;近年来分析PCBs的前处理方法,主要包括加速溶剂萃取、超临界流体萃取、微波萃取、固相微萃取、基质分散固相萃取等提取方法和固相萃取小柱、凝胶渗透色谱等净化方法;目前气相色谱和气相色谱-质谱联用技术发展以及一些新技术在分析PCBs方面的应用,包括全二维气相色谱法、快速气相色谱法、气相色谱-离子肼串联质谱法、高分辨气相色谱-高分辨质谱法等。总结了国内外PCBs的研究现状。

| Abstract: | Determination of polychlorinated biphenyls (PCBs) is always difficult due to their existence in quite small residue concentration in various environmental media and suffering lots of interference from the complex matrix composition. Therefore, it is essential to select the suitable sample pretreatment methods and advanced detection techniques for analysis of PCBs in environmental samples. This review is focused on the demonstration of characteristics and the main sources of PCBs, the sample pretreatment techniques including ASE, SFE, MAE, SPME, MSPD and the sample purification techniques such as SPE and GPC. The recent development on GC and GC-MS techniques, the most recent applications of some advanced technologies such as GC×GC, fast GC, GC-IT-MS/MS, HRGC-HRMS in PCBs analysis are also presented. This review also summarizes the latest research progress on PCBs analysis worldwide. |
