摘要
土壤和沉积物中挥发性有机物潜在危害大,应优先控制的污染物。本论文以5种挥发性卤代烃(二氯甲烷、三氯甲烷、四氯化碳、三氯乙烯、四氯乙烯)和9种挥发性苯系物(苯、甲苯、乙苯、苯乙烯、间对二甲苯、邻二甲苯、1,2二氯苯、1,3二氯苯、1,4二氯苯)为目标研究对象,用顶空-气相色谱/质谱联用法进行分析。结果表明5种挥发性卤代烃和9种挥发性苯系物的检出限在0.5~1.7μg/kg范围内,标准曲线线性范围为0.9977~0.9996,回收率在92.5%~106.6%之间,结果符合应用要求。
Volatile organic compounds（VOCs） in soil and sediment are potentially harmful and should be controlled first. Five volatile halogenated hydrocarbons（dichloromethane, trichloromethane, carbon tetrachloride, trichloroethylene, tetrachloroethylene） and nine volatile benzene series（benzene,toluene, ethylbenzene,styrene,m-xylene,p-xylene,o-xylene,1,2-dichlorobenzene,1,3-dichlorobenzene,1,4-dichlorobenzene）for the target research object,there were analyzed by headspace gas chromatography/mass spectrometry.The results showed that the detection limits of 5 volatile halogenated hydrocarbons and 9 volatile benzene series were in the range of 0.5~1.7μg/kg, the linear range of the standard curve was 0.9977~0.9996,and the recovery was 92.5%~106.6%.the results accorded with the application requirements.
