【Abstract】 Coke oven gas sample was collected with filter film of glass fiber. The organic components of the sample were extracted by Soxhlet’s extraction or ultrasonic extraction with dichloromethane, then analyzed by GC - MS. Effects of the two extraction methods were studied. Many kinds of polycyclic aro- matic hydrocarbon compounds such as benzo[a] pyrene were detected. Some of them were quantitatively determined.更多还原
