| Abstract: | Extractive and detective method of polycyclic aromatic hydrocarbons(PAHs) in groud soil aroud working well at oilfield is researched.Different extractive ways are experimented,such as ultrasonic extraction,microwave assisted ultrasonic extraction and microwave and surge assisted ultrasonic extraction.Among them,ultrasonic extraction shows the best extraction efficiency with optimal extractive parameters as follows: time 60 min,power 120 w and water temperature 30 ℃.When compared with that of 72 h soxhlet extraction,it also outweighs.Therefore,ultrasonic extraction is chosen as the best extractive method. |
