Covalent organic framework-based sorptive extraction for pesticide and phenolic residues in complex matrices

초록

The development of novel sample preparation media is crucial for the efficient analysis of hazardous components like pesticide and phenol residues. To facilitate the extraction and enrichment of these residues from complex samples, various functionalized materials have been prepared as adsorbents. Recently, covalent organic frameworks (COFs), a class of functionalized porous organic materials, have emerged as promising adsorbents owing to their high surface area, tunable porosity, and specific recognition properties for pesticides and phenols. These advanced porous organic materials, when paired with modern analytical techniques, have been successfully applied to the analysis of pesticide and phenol residues in complex matrices, including environmental, food, and biological samples. This review encapsulates recent progress in this field. Finally, current challenges and future research directions are discussed to inform the advancement of next-generation COF-based adsorbents.
