ABSTRACT
Objective To develop a method of determining benzene hydrocarbon and halogenated alkane hydrocarbon in the air of workplaces with the capillary gas chromatography of carbon disulphide desorption. Methods Benzene hydrocarbon and halogenated alkane hydrocarbon in the air of workplace were collected by active carbon sampling cuvette, then separated by hydrogen flames detector gas chromatography machine after carbon disulphide desorption. Benzene hydrocarbon and halogenated alkane hydrocarbon were determined quantitively by retention time and quantitatively by apex area. Results The linear ranges of benzene, toluene, p-xylene, m-xylene, o-xylene, ethyl benzene, styenl, chlorobenzene, acetone, carbontetrachloride, dichloromethanl, trichloromethane, 1, 2-dichloroethane, naphth alene were 0.019-81.600, 0.018-91.200, 0.018-88.800, 0.018-56.8, 0.011-92.000, 0.012-63.200, 0.018-93.200, 0.449-2298.400, 0.252-1287.000 and 0.076-390.000 mg/m3 respectively. The recovery rates were 88.4%-98.6% and RSD were 1.0%-6.0%. Conclusion This method can separate efficiently and determine accurately benzene hydrocarbon and halogenated alkane hydrocarbon in the air with a good precision. It is suitable for the determination of the toxicants in the air.
