| 摘 要： | 利用吹扫捕集-GC/MS法对引起南宁市竹排冲河道水体黑臭的嗅味物质进行检测分析。结果表明,导致竹排冲水体黑臭的嗅味物质主要为苯系物、硫类化合物和氯苯类化合物,其中甲硫醚(相对含量1.70%)、二甲基二硫醚(相对含量3.19%)、甲基丙基二硫醚(相对含量6.11%)等挥发性有机物为竹排冲水体中的主要致嗅物质,是竹排冲水体嗅味产生的主要原因。

| Abstract: | The purge and trap pretreatment technique and GC/MS method were used to determine the typical odorous compounds in Zhupai Creek,Nanning city.Results show that the main odorous compounds in Zhupai Creek are benzene homologues,sulfide compounds and Chlorobenzene compounds.Some sulfide compounds such as dimethyl sulfide(relative content 1.70%),dimethyl disulfide(relative content 3.19%),methyl propyl disulfide(relative content 6.11%) and other volatile organic substances are the main odorous compounds which cause the odorous smell in Zhupai Creek. |
