Title: Determination of 11 Kinds of Halogenated Alkane Hydrocarbon in Drinking Water with Headspace Gas Chromatography
Abstract: Objective To establish the method of determining halogenated hydrocarbon in drinking water with headspace gas chromatography.Methods Halogenated hydrocarbon in the water were extracted by headspace technology(oven temperature: 70 ℃,vial equilibrium time: 20 min,NaCl: 380 g/L),then analyzed with Rtx-1701 capillary column,then were determined with GC by controlling the temperature.Retention time of the peaks was used for qualitative analysis,while external standard method was used for quantitative analysis.Results The linear ranges of 1,1-dichloroethylene,dichloromethane,trans-1,2-dichloroethylene,cis-1,2-dichloroethene,trichloromethane,1,1,1-trichloroethane,carbon tetrachloride,1,2-dichloroethane,trichloroethylene,dichloromomethane,1,2-dibromoethene,tetrachloroethylene,1,1,2-trichloroethane,dibromochloromethane,tribromomethane,1,3-dichlorobenzene,1,4-dichlorobenzene,1,2-dichlorobenzene,1,3,5-trichlorobenzene,1,2,4-trichlorobenzene,hexachlorobutadiene 1,2,3-trichlorobenzene,1,2,4,5-tetrachlorobenzene,1,2,3,4-tetrachlorobenzene,pentachlorobenzene,hexachlorobenzene were 0.013-742.4 μg/L,the limit of detection were 0.001 2-1.10 μg/L,the rates of recovery were 85.2%-113.8% and RSDs were 1.7%-7.1%.Conclusion This method is simple,rapid,sensitive,accurate and applicable to the simultaneous determination of 26 kinds of halogenated hydrocarbon in the water.
