Title: Determination on 14 kinds of halogenated hydrocarbon in drinking water by headspace gas chromatography
Abstract: Objective To establish a method for determining halogenated hydrocarbon in drinking water with headspace gas chromatography.Method Halogenated hydrocarbon in the water were extracted by headspace technology(equilibrium temperature was 70 ℃,vial equilibrium time was 45 min),application HP-5 capillary column(60m*0.32mm*0.25μm) and determined with GC by temperature programming.Retention time of the peaks was used for qualitative analysis and external standard method was used for quantitative analysis.Results The detection limit 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,dibromochloromethane,chloroethylene,tetrachloroethylene,tribromomethane were during 0.01μg/L to 3.15μg/L,the average recovery were during 92% to 110.6% and RSDs were 2.7% to 6.0%.Conclusions This method was convenient,rapid,sensitive and applicable to simultaneous determination 14 kinds of halogenated hydrocarbon in the water,and the method accord with the national standard of organic matter in drinking water.
