GC/MS法测定黄浦江水中挥发性有机化合物

采用吹扫捕集装置与GC／MS联用仪的全自动恒流控制，对黄浦江7个断面水样中47种挥发性有机化合物进行了分析。结果表明，被查的47种挥发性有机化合物基本都有检出，其中甲苯、异丙苯的绝对检出量最高。四氯化碳的检出值也较高，吴淞口四氯化碳的平均浓度已经远远超过GB3838—2002《地表水环境质量标准》，并且四氯化碳浓度在黄浦江流域各个断面的分布具有一定规律性。

To Detect Volatile Organic Compoundin Waterin Huangpujiang River With GC/ MS

Using blowing and arresting device and GC/MS, full automatic permanent current control, 47 kinds of volatile organic compound in water sample from 7 cross section in Huangpujiang River was analyzed. 47 kinds of volatile organic compound were all be detected. The detection rate of toluene and isopropyl benzene were highest, and CCl_4 was high, even in Wusongkou, the mean concentration of CCl_4 was great more than the demand of Surface Water Environment Quality Standard (GB 38382002). The distribution of CCl_4 in 7 cross section have a certain rule.
