摘要
硝基芳烃类有机物是一类重要的化工原料,也是性质相对稳定、难以降解的高毒污染物。其检测技术主要有分光光度法、电化学法、液相色谱法、气相色谱-电子捕获检测器法(GC/ECD)、气相色谱-质谱法(GC-MS)等。其中GC/ECD法和GC-MS法因测定准确、灵敏、适用范围广而得到广泛应用。该文从不同类型水体中硝基芳烃类有机物样品的采集、前处理以及检测分析技术的选择角度,对硝基芳烃类有机物检测技术的发展进行了简要评述,同时对其分析方法进行了展望。
Nitroaromatics, as a kind of organic compounds, are a class of important chemical raw materials, which are also highly toxic pollutants with stable structures and difficult degradation. The main detection techniques for nitromatics were spectrophotometry, electrochemistry, high pressure liquid chromatography （ HPLC ）, gas chromatography - electron capture detection （ GC - ECD ） and gas chromatography - mass spectrometry （GC - MS）. Among them, GC - ECD and GC - MS were more widely used because of their accuracy, sensitivity and wide application. In this paper, the re- search progress on aromatic compounds in different types of water matrixs in the aspects of sampling, pretreatment and determination methods were briefly reviewed. The new detection techniques for aro- matic compounds were also prospected.
