摘要:
近年来，严重的恶臭污染扩散事件带来诸多环境与健康问题并引起了广泛的社会关注。针对环境中恶臭污染物现场检测的需要，开展了基于电晕放电离子迁移谱（CD-IMS）的恶臭污染物检测方法研究。搭建了CD-IMS检测系统并优化了工作参数，在优化的参数下对常见硫系恶臭污染物单一样品及混合样品进行了检测。甲硫醚、二甲二硫醚和甲硫醇的理论检出限分别为0.93×10-3、0.019、0.144 mg/m3（3倍信噪比），线性范围分别为0.03-0.15、0.2-4.0、0.4-4.0 mg/m3，相对标准偏差均小于2.5%。
Abstract:
Serious malodor pollution e vents bring many environmental and health problems and have aroused broad social concern. In view of the need for on-site detection and component analysis of malodor, the corona discharge ion mobility spectromet er (CD-IMS) was proposed for malodor detection. T he parameters of the system were optimized and dimethyl sulfide, dimethyl disulfide, methyl mercaptan and the mixture of them were detected. The detection limits (3 times the baseline noise) of 0.93×10-3, 0.019 and 0.144 mg/m 3, the linear ranges of 0.03-0.15, 0.2-5.0 and 0.4-1.0 mg/m3, the correlation coefficients (r 2) of 0.996, 0.994 and 0.990 were obtained for dimethyl sulfide, dimethyl disulfide and methyl mercaptan, respectively. The relative standard deviation (RSD) for the malodor was below 2.5%
