摘要
建立了吹扫捕集-气相色谱-质谱联用法测定水中一氯代苯、1,2-二氯苯、1,4-二氯苯、1,3,5-三氯苯、1,2,4-三氯苯、1,2,3-三氯苯6种氯苯类有机物的方法。6种氯苯类有机物的质量浓度与其峰面积在一定的浓度范围内呈良好线性关系,方法的检出限为0.002~0.005μg/mL。加标回收率为93.0%~96.5%,测定结果的相对标准偏差为3.12%~6.08%。该法可以满足水中该类有机物的测定。
The method of determination chlorobenzcne compounds in water by purge and trap concentrator with gas chromatography mass spectrometry was established. The concentrations of six kinds of ehlorobenzenes compounds had good relationship with peak area at a certain concentration range. The detection limits were 0. 002 -0.005μg/mL. The recoveries were 93.0% -96.5%, and the relative standard deviations of determination results were 3.12% - 6.08% ( n = 7 ). The method is suitable for determination of chlorobenzenes compounds in water sample.
