摘要：
A comparative study on the extraction of 16 polynuclear aromatic hydrocarbons (EPA priority pollutants) from urban atmospheric particulates was conducted employing the Soxhlet and the ultrasonic technique with various solvents. Ultrasonic extraction using acetonitril appeared to meet most requirements since it combined high recovery rates for most PAHs with simplicity in use. The extraction procedure was optimized regarding the duration of sonication, the solvent amount and the number of extraction treatments.
