【摘要】 采用热脱附-气相色谱/质谱联用法对4辆处于静止状态下的车辆内部空气中挥发性有机物(VOCs)进行了研究,共定性检出了48种有机物,其中C6~C9之间的组分较多;并对VOCs的总浓度进行了定量,1#~4#车分别为1846、2289、1104和3146μg/m3;其中BTEX占VOCs总量的20%~30%;车内VOCs浓度与温度及车辆使用年限密切相关。更多还原

【Abstract】 A study of volatile organic compounds in 4 automobiles were conductedly with TD-GC/MS, 48 pollutants were qualitatively determined, and found that these contaminants are mostly belong to C₆^C₉.Concentration of the total VOCs was also measured.The values are 1846, 2289,1104 and 3146 μg/m³ from 1^# to 4^# car in turn; the percentage of BTEX to concentration of total VOCs is 20%³0%; the concentration of the total VOCs is related to temperature and the ages of automobiles.更多还原
