Preparation of core-shell structured magnetic covalent organic framework nanocomposites for magnetic solid-phase extraction of bisphenols from human serum sample

Core-shell structured magnetic covalent organic framework (Fe3O4@COF) nanocomposites were synthesized by a facile approach and explored as a new absorbent for magnetic solid-phase extraction (MSPE) of bisphenols (BPs) from human serum sample.167
