摘要	Volatile chlorobenzenes (CBs) is an organic pollutant which exists ubiquitously in the environment. Ion Mobility Spectrometry (IMS) has been a powerful technique for quick ion-separation and detection under ambient pressure. In this paper, atmospheric chlorobenzene, p-dichlorobenzene, o-dichlorobenzene and m-dichlorobenzene were detected by a homemade Vacuum Ultraviolet Field Asymmetric Waveform Ion Mobility Spectrometry (UV-FAIMS). The CV-I spectra under different Dispersion Voltage (DV) were obtained, then the CV-DV fingerprints spectra of the four substances were synthetized. Base on the fingerprint spectra, optimal separation and detection parameters of three isomers: dichlorobenzene, o-dichlorobenzene, m-dichlorobenzene were determined. The results showed that under the DV of 800 and 1 000 V, three substances could be effectively identified at CV of 20.4 V (DV=800 V), 3. 2 V(DV=800 V) and 11. 9 V(DV=1 000 V), respectively, by selecting the characteristic peaks. The influences of flow rate on FWHM and peak position of FAIMS spectrum were studied and the results provided a reference for flow optimization. The limit of detection (LOD) of UV-FAIMS investigated by using different concentrations of dichlorobenzene at DV=450 V and CV=4. 3V was lower than 0. 05 mg . m(-3). This paper provides a rapid and accurate detection method for halogenated benzene pollutant and other isomers of benzene.
