- 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%
