【摘要】 采用毛细管气相色谱法同时分离测定水中11种氯苯类化合物。用DB-23毛细管柱分离,电子捕获检测器检测,方法线性关系良好,水中氯苯类的最低检出限分别为:二氯苯0.74μg/L~0.89μg/L,三氯苯0.17μg/L~0.21μg/L,四氯苯0.07μg/L~0.11μg/L,五氯苯0.04μg/L、六氯苯0.02μg/L,加标回收率在83.5%~101%之间,RSD在1.4%~5.2%之间。更多还原

【Abstract】 A method is for 11 kinds of chlorobenzenes determination in water samples which separated by DB-23 fused silica capillary column and detected with GC-ECD.The linear relation between instrument responds and calibration standard was excellent.The limits of detection of dichlorobenzenes in water sample were 0.74 μg/L~0.89 μg/L respectively,trichlorobenzenes 0.17 μg/L~0.21 μg/L,tetrachlorobenzenes 0.07 μg/L~0.11 μg/L,pentachlorobenzene 0.04 μg/L and hexachlorobenzene 0.02 μg/L.The recovery range was between 83.5%~101%,RSD 1.4%~5.2%.更多还原
