| Abstract: | The food quality detection and determination is a very important problem that have widely attracted people’s special attention.The food analysis deals with the nutritional component,additive,agricultural chemical residue and heavy metal impurity analysis etc.In this paper,the application of some environment-friendly "green" extraction technique combined with atomic absorption spectrometry in food analysis is introduced.These "green" extraction technique includes solid phase extraction(SPE),single-drop microextraction(SDME),dispersive liquid-liquid microextraction(DLLME),cloud point extraction(CPE),room temperature ionic liquid extraction(RTILE) as well as molecularly and ionic imprinted polymer extraction(MIPME and IIPME).50 references were cited. |
