摘　　要：采取超声波萃取法、微波萃取法和加压流体萃取法提取塑料中16种多环芳烃,比较3种前处理方法的提取能力。对3种前处理方法的精密度、检出限、定量限、加标回收率和相对标准偏差进行对比分析和验证。结果表明,除了萘之外,3种前处理方法对其他15种目标物的回收率和准确度相当,得出的数据之间差异性不大,均可满足对塑料样品的检测需求。To compare the determination of 16 polycyclic aromatic hydrocarbons(PAHs)from plastics by ultrasonic extraction,microwave extraction,and pressurized fluid extraction.The precision,detection limit,determination lower limit,and spiked recovery rate were comparatively analyzed and validated.Except for naphthalene,the recoveries and accuracy of the other 15 target substances are equivalent,and there are no evident difference among the data obtained by the three pre-treatment methods,which all can meet the testing requirements for plastic samples.
