Synthesis of magnetic metal–organic framework composites, Fe3O4-NH2@MOF-235, for the magnetic solid-phase extraction of benzoylurea insecticides from honey, fruit juice and tap water samples

Herein, a novel, fusiform-like magnetic metal–organic framework material (Fe₃O₄-NH₂@MOF-235) was fabricated by a facile two-step solvothermal approach.
