Abstract

SPME methods are now extremely popular. Recent advances in SPME have focused on the development of new materials as sorbent coatings capable of providing high extraction efficiencies, as well as high selectivity with high mechanical and chemical stability. Metal-organic frameworks (MOFs) have become an extremely popular material due to their unique properties (large surface area, selective gas adsorption, tunable structures, high thermal and chemical stability). This review summarizes the current status of MOF use in terms of fiber preparation, extraction performance and the applicability of SPME in air sample analysis. The analytical performance of MOF-based SPME fibers in the described air analysis applications is characterized by high extraction efficiency, adequate reproducibility, high sensitivity and acceptable reusability. In comparison with commercial coatings, MOF-based fibers tend to have better performance. Nearly all reported applications focused on HS testing and in all cases in combination with GC.

微萃取过程中使用的固体支持物和新型先进材料基于金属有机框架的固相微萃取用于空气样品分析：微型综述

SPME 方法现在非常流行。SPME 的最新进展主要集中在开发新材料作为吸附剂涂层，这种材料能够提供高萃取效率、高选择性以及高机械和化学稳定性。金属有机框架（MOFs）因其独特的性能（大表面积、选择性气体吸附、可调结构、高热稳定性和化学稳定性）已成为一种非常受欢迎的材料。本综述从纤维制备、萃取性能以及 SPME 在空气样品分析中的适用性等方面总结了 MOF 的使用现状。基于 MOF 的 SPME 纤维在所述空气分析应用中的分析性能特点是萃取效率高、重现性好、灵敏度高且可重复使用。与商用涂层相比，基于 MOF 的纤维往往具有更好的性能。几乎所有报告的应用都集中在 HS 测试上，而且在所有情况下都与 GC 结合使用。
