摘　　要：针对恶臭污染物现场快速检测需求,开展了基于电晕放电离子迁移谱(CD-IMS)技术的恶臭污染物检测方法研究,搭建了CD-IMS检测系统,优化了工作参数,对常见硫系恶臭物(甲硫醚、二甲二硫醚和甲硫醇)单一样品及混合样品进行了检测,得到了该检测系统对上述3种恶臭物的理论检出限、线性工作范围及相对标准偏差.混合样品检测结果表明,离子迁移谱技术能够实现对恶臭污染物的成分分析,可用于恶臭污染物的现场检测.A corona discharge ion mobility spectrometry(CD-IMS) detection system was established to detect malodor,and its working parameters were optimized. Single and mixed samples of common malodor compounds(dimethyl sulfide,dimethyl disulfide and methyl mercaptan) were detected. The theoretical limit of detection,linear working range and relative standard deviation(RSD) of these three malodors were obtained. The detection results showed that the ion mobility spectrometry technology could realize the component analysis of mixed malodor,and the field detection of malodor based on this technology had a certain feasibility.
