An easy and environmental friendly method, based on the use of magnetic molecular imprinted polymers (mag-MIPs) is proposed for the simultaneous extraction of the 16 U.S. EPA polycyclic aromatic hydrocarbons (PAHs) priority pollutants. The mag-MIPs based extraction protocol is simple, more sensitive and low organic solvent consuming compared to official methods and also adequate for those PAHs more retained in the particulate matter. The new proposed extraction method followed by HPLC determination has been validated and applied to different types of water samples: tap water, river water, lake water and mineral water.
本文提出了一种基于磁性分子印迹聚合物（mag-MIPs）的简便且环保的方法，用于同时萃取美国环保署（EPA）规定的16种多环芳烃（PAHs）优先污染物。与官方方法相比，基于mag-MIPs的萃取方案简单、灵敏度更高且有机溶剂消耗量低，同时也适用于那些在颗粒物中保留较多的PAHs。新提出的萃取方法结合高效液相色谱（HPLC）测定已得到验证，并应用于不同类型的水样：自来水、河水、湖水和矿泉水。
