| 摘 要： | 采用二次热解吸／气相色谱／质谱联用测定石化工业区大气环境中挥发性有机物，质谱检测器同时进行全扫描和选择离子扫描，全扫描定性，选择离子扫描和内标法定量。方法线性良好，50种目标化合物的检出限为0.14ng-2.45ng，在3个浓度水平的加标回收试验中，1，1-二氯乙烯和二氯甲烷回收率较低，氯仿和苯低浓度回收率较差，其余46种目标化合物的回收率为83.4％-116％，RSD为0.5％-8.9％。

| Abstract: | The volatile organic compounds in the air of petrochemical industry zone were determinated by two-stage thermal adsorption / gas chromatography / mass spectrometry.The full-scan was performed for qualitative analysis of and selected ion monitoring(SIM) and internal standard were applied for quantitative analysis.The good linearity of the method was achieved.The detection limits of 50 target compounds were from 0.14 ng to 2.45 ng.It was found the low recoveries of 1,1-dichloroethene and dichloromethane at th... |
