摘要: 为了建立石化行业土壤中挥发性有机物(VOCs)的分析方法,研究了国内外土壤中VOCs的分析标准,综述了土壤中VOCs的前处理技术和检测方法,并对建立石化行业土壤中VOCs分析方法提出建议。我国目前已有7项土壤中VOCs的分析标准,但涵盖的VOCs种类偏少,分析对象主要为卤代烃和芳烃。土壤中VOCs的前处理技术主要有溶剂萃取、顶空、吹扫捕集和固相微萃取等,检测方法有GC-FID,GC-MS,GC-PID。由于石化行业土壤中VOCs污染物种类不仅包括卤代烃和芳烃,还可能会有酮类、醛类、烷烃、环烷烃、烯烃等,因此需要根据不同的污染物种类建立对应的分析标准,并探索适合石化行业的土壤中VOCs前处理技术和检测方法。

Abstract: For the development of detection technologies for volatile organic compounds (VOCs) in soils in petrochemical industry, analytical standards, pretreatment technologies and detection methods at home and abroad were investigated, and several proposals were proposed. Seven analytical standards about VOCs in soils were developed in our country, but the types of VOCs were mainly about halogenated and aromatic hydrocarbons. Solvent extraction, headspace sampling, purge and trap, and solid-phase microextraction were included in the pretreatment technologies, and detection methods mainly contained GC-FID, GC-MS and GC-PID. However, not only halogenated hydrocarbons and aromatic hydrocarbons, but also ketones, aldehydes, alkanes, naphthenic hydrocarbons, olefins might be included in petrochemical industry, therefore, it is necessary to establish corresponding analysis standards according to different types of pollutants, and explore VOCs pre-treatment technology and detection methods suitable for the petrochemical industry.
