摘要
回顾了近年来研究人员在苯并[a]芘检测过程中的前处理方法的研究概况,对比了各方法的优缺点.苯并[a]芘检测过程中的前处理方法主要有液液萃取、索氏提取、固相萃取、凝胶渗透色谱净化、超声萃取、微波辅助萃取等,检测涉及的样品主要为水、油、土壤及各种食品等.每种前处理方法都有一定的适用范围,在实际检测过程中可根据样品的性状以及苯并[a]芘在该样品中的存在形态选择合适的检测方法.
Abstract
The paper reviewed pretreatment methods during benzo(a) pyrene test process,and analyzed advantages and disadvantages of each method.Pretreatments mainly included liquid-liquid extraction,soxhlet extraction,solid-phase extraction,gel permeation chromatography ultrasonic extraction,and microwave-assisted extraction.The main samples were water,oil,soil,and food etc.Each pretreatment had a certain scope of application,which can be selected according to the sample's property and benzo(a) pyrene exist state in the sample.
