Abstract

Sample pretreatment is considered the most significant procedure in analyzing and detecting trace targets from complicated matrices. Aerogels display remarkable properties, such as a low density, porous structure, high surface area, excellent adsorption performance, and good thermal stability, making the aerogels exploitable as extraction materials for sample preparation. This review summarizes the classification, development, and application of aerogels for solid-phase extraction (SPE) and solid-phase microextraction (SPME) from 2010 to 2021. Different aerogel types were introduced in SPE and SPME, such as silica, carbon, organic, organic–inorganic hybridized, and metal–oxide aerogels. The aerogel-based sorbents effectively captured a wide variety of analytes in environmental, biological, and food samples due to their excellent properties and flexible adsorption performance. Current challenges and future prospects for aerogels in sample preparation are also proposed.

气凝胶在固相萃取和微萃取中的研究进展

样品预处理是分析和检测复杂矩阵中痕量目标的最重要的步骤。气凝胶具有低密度、多孔结构、高比表面积、优异的吸附性能和良好的热稳定性等特点，可作为样品制备的提取材料。本文综述了2010年至2021年气凝胶在固相萃取(SPE)和固相微萃取(SPME)中的分类、发展和应用。在SPE和SPME中引入了不同类型的气凝胶，如二氧化硅气凝胶、碳气凝胶、有机气凝胶、有机-无机杂交气凝胶和金属-氧化物气凝胶。由于其优异的性能和灵活的吸附性能，气凝胶基吸附剂有效地捕获了环境，生物和食品样品中的各种分析物。最后提出了气凝胶在样品制备中的挑战和前景。
