| 摘 要： | 本文主要对食品添加剂中重金属检测的前处理方法以及检测方法进行综述。目前,重金属前处理方法主要包括干法灰化、湿法消解、微波消解、液液萃取等,其中干法消解、湿法消解作为常用的前处理方法,耗时较长且容易造成损失,而微波消解具有方便、快速、干扰小等特点,逐渐得到认同与推广。重金属检测方法主要包括:快速显色法、原子吸收分光光度法、原子荧光分光光度法、电感耦合等离子体检测法等,后者以其较好的准确度与精密度,受到越来越多学者的追捧。

| Abstract: | This article focused on the research progress of heavy metal's sample preparation and testing methods in food additive. The main sample preparation methods contained:dry digestion,wet digestion,microwave digestion,solvent extraction and so on. Dry digestion and wet digestion were both time and sample consuming.Microwave digestion was widely used in the test due to its convenient,fast,little interference. Heavy metal's main analysis methods included:rapid colorimetric method,atomic absorption spectrophotometry,atomic fluorescence spectrometry,inductively coupled plasma detection method and so on. The last method was used wildly by more and more researchers due to its higher accuracy and precision. |
