Modified superhydrophobic magnetic Fe3O4 nanoparticles for removal of microplastics in liquid foods

•Fe3O4 modified with saturated long-chain fatty acid was successful for MPs removal.•Ingredients in beverages can affect the removal efficiency of MPs.•The developed adsorption kinetic equation can predict the value of adsorption of MPs.•Electrostatic interaction, and van der Waals force were main forces.
