Abstract :
Magnetic Covalent Organic Frameworks are one of the adsorbents used in Magnetic Solid-Phase Extraction, which are due to easy synthesis, compatibility with the environment, high porosity, easy changes of functional groups and structures. pre-engineered, have been widely used in food extraction and analysis. In this paper, the polymer-based MSPE method of MCOF will be described. Also, the latest design and fabrication methods of various MCOFs will be briefly explained. is given. The development and application of MCOFs combined with MSPE technology shows great potential in food safety monitoring. MCOFs are due to their unique structural and chemical properties such as strong magnetic properties, high specific surface area, functional groups, permanent porosity and Excellent chemical stability, excellent magnetic adsorbent are considered. Functional groups of MCOFs with monomers or polymers that contain different functional groups are a scientific approach to develop new MCOFs that can effectively adsorb contaminants in food. Effectively texture effect. removes, and improves extraction efficiency. This review describes the recent progress in the application of MCOFs in the preconcentration and analysis of pesticides, pharmaceuticals, polymer additives, pyrolysis products and other types of food contaminants. Finally, it examines future challenges and possible solutions in the analysis of the food samples.
