Method for extracting polycyclic aromatic hydrocarbon from PET product

The invention discloses a method for extracting polycyclic aromatic hydrocarbon from a PET product. The method comprises the following steps of: a, crushing the PET product into particles; b, weighinga predetermined amount of crushed PET particle sample, putting the sample into a transparent top-empty jaw bottle, adding 98% concentrated sulfuric acid and a 2, 5-di-tert-butylhydroquinone solutionwith the mass percent concentration of 10%, and performing ultrasonic dissolution in a water bath at 35-45 DEG C to obtain a to-be-treated sample I; and c, mixing water, acetonitrile, cyclohexane andSCX filler, rapidly adding the mixture into the to-be-treated sample I, performing vortex mixing, and performing centrifugal extraction to obtain an upper organic phase. The extraction method providedby the invention has the characteristics of rapidness, simplicity, convenience, low cost, low interference, low instrument loss and the like. 本发明公开了一种PET制品中多环芳烃的提取方法，包括以下步骤：a.将PET制品粉碎成颗粒；b.称取预定量粉碎后的PET颗粒样品至透明顶空钳口瓶中，加入98％浓硫酸、质量百
