Solid-Phase Microextraction Fibers Based on Novel Materials:Preparation and Application

固相微萃取(SPME)是一种简便、快速、绿色的样品前处理方法,近年来引发了广泛关注。固相微萃取探针的萃取相对其萃取选择性和效率起着决定性作用,因此一系列物理化学性质优秀的新型固相微萃取涂层材料应运而生,被用于制备新型固相微萃取探针,以对不同样品基质中的有机小分子进行检测。本文概述了近年来新型SPME探针的研制所依托的新型材料,包括聚合物材料、碳材料、金属有机框架材料等,并重点阐述了相关材料的制备与固定方法、微观结构与萃取性能,以及所制备探针在环境分析、纺织品和皮革分析、食品分析等领域中的应用,并进一步对新型固相微萃取涂层今后的开发方向和应用前景进行了展望。

Convenient,rapid as well as environmentally-friendly,solid-phase microextraction is（ SPME） a sample preparation technique,which draws widespread attention among the scientific community. The extraction phases in the SPM E fibers determine their selectivity and extraction efficiency,hence,a series of newfiber coatings with excellent physical and chemical properties are developed for detection of various small organic molecules in complex sample matrices. Herein,we give a brief reviewof some materials widely used for the preparation of newSPM E fibers,including polymers,carbonaceous materials,metal-organic framework,and some other materials, with the emphasis on the fiber preparation methodologies, the microstructures and extraction properties of the novel fiber coatings, together with applications of the synthesized fibers on environmental analysis, food analysis and inspection on textile and leather samples. Furthermore, future developing trends and application prospects of the newfiber coatings are discussed.
