目的建立水质检测106项中9种卤代烃同时测定的方法。方法采用顶空气相色谱,应用Hp-5毛细管柱和电子捕获检测器进行检测。结果顶空气相色谱法对9种卤代烃混合标准溶液系列相关系数均在0.999以上,平均回收为90.6%~102.5%,相对标准偏差为1.01%-5.58%,结论研究方法一次性完成饮用水中9中卤代烃的分离和测定,简单、快速和灵敏,同时有较好的准确度和精密度。 Objective To establish a method for simultaneous determination of 9 halocarbons in 106 water quality tests. Methods Headspace gas chromatography was used to detect Hp-5 capillary column and electron capture detector. Results The headspace gas chromatography had a correlation coefficient above 0.999 for the nine kinds of halogenated hydrocarbon mixed standard solutions with the average recovery of 90.6% -102.5% and the relative standard deviation of 1.01% -5.58%. Conclusions The research method can complete the drinking water The separation and determination of halohydrocarbons in 9 are simple, fast and sensitive with good accuracy and precision.
