摘　　要：基于气相色谱-质谱联用(GC-MS)方法,对南京市2家钢铁企业焦化工艺的挥发性有机物(VOCs)无组织排放情况开展监测。结果表明:焦化行业排放的VOCs主要组分为苯系物、含氧化合物、卤代烃、烷烃和烯烃,分别约占33%、24%、16%、13%和13%,炔烃约占1%;主要特征污染物包括苯、甲苯、二甲苯、甲醇、乙醛、丙酮、氯乙烯、二氯乙烯、三氯苯等。In this paper,VOCs emissions from coking chemical industry of two steel companies in Nanjing were determined by GC-MS. The results showed that the main components of VOCs were BTEX,Oxygenated organic compounds,Halogenated hydrocarbon,Alkanes and Olefin,which accounting for 33%,24%,16%,13%and 13%,respectively. The main characteristic VOCs from coking chemical industry included Benzene,Toluene,Xylene,Methanol,Acetaldehyde,Acetone,Vinyl Chloride,Dichloroethylene,Trichlorobenzene,etc.
