摘要
目的:建立胶粘剂中二氯甲烷,1,2-二氯乙烷,三氯乙烷,三氯乙烯4种卤代烃的气相色谱检测法。方法:样品经乙酸乙酯提取,毛细管柱分离,氢火焰检测器检测。结果:4种卤代烃的平均回收率为96.6%～104%,相对标准偏差(RSD)为1.98%～3.31%,最低检测限为0.05 g/kg～0.1 g/kg,浓度在1.0μg/L～200μg/L范围内呈线性关系,相关系数均大于0.9995。结论:该方法简便、高效、稳定,适合粘胶剂中这4种卤代烃的测定。
Objective：To establish a method for determining four kinds of halogenated hydrocarbons,including dichloromethane,1,2-dichloromethane,trichloroethane,trichloroethylene in adhesive by gas chromatography.Methods：The samples were extracted by ethyl acetate and separated by capillary column and detected by flame ionic detector.Results：The average recoveries of four kinds of halogenated hydrocarbons ranged from 96.6% to 104% with a relative standard deviation（RSD） between 1.98% and 3.31%.The detection limit of this method for halogenated hydrocarbons ranged from 0.05 g/kg to 0.1 g/kg and linear range was 1.0 μg/L～200 μg/L,with all correlation coefficient 〉0.9995.Conclusion：The method is simple,high effective and stable,and it is appropriate for determination of the 4 halogenated hydrocarbons,in adhesives.
