顶空-气相色谱法同时测定生活饮用水及水源水中氯苯类化合物

Determination of 6 Chlorobenzene Compounds In Drinking Water By Head-Space GC

采用顶空-气相色谱法同时测定生活饮用水及水源水中1,2-二氯苯、1,4-二氯苯、1,2,3-三氯苯、1,2,4-三氯苯、1,3,5-三氯苯、六氯苯6种氯苯类化合物。测定结果的相对标准偏差为1.6%～2.8%。回收率为95.9%～100.4%。通过实样分析验证了方法的适用性。

Head-Space GC was applied to the determination of 6 chlorobenzene compounds in drinking water and source water at the same time ,such as o-Dichlorobenzene, p-Dichlorobenzene, 1,2,3-trichlorobenzene, 1,2,4-trichlorobenzene, 1, 3,5-trichlorobenzene and Hexachlorobenzene. RSD’s of these chlorobenzene compounds found by the precision test were in the rang from 1.6%to 2.8%. Recoveries found by standard addition method were in the rang of 95.9%to 100.4%. The feasibility of this method was proved by the analysis of some water samples.
