Magnetic covalent organic frameworks for extraction and determination of endocrine‐disrupting chemicals in beverage and water samples

Magnetic covalent organic frameworks (Fe₃ O₄ @COFs) with good MSPE performance for phenolic EDCs were synthesized by the solvothermal method. The magnetic covalent organic framework-based MSPE-HPLC-UV method was applied successfully to determine phenolic EDCs in beverage and water samples with satisfactory recoveries (90.200%-123%) and relative standard deviations (2.100%-12.100%). © 2023 Society of Chemical Industry.
