Magnetically active ultrafiltration membranes are developed to reduce the concentration polarization effect. For this purpose, the surface of industrial cellulose membranes are activated for the polymer spacer grafting and the following immobilization of Fe3O4 nanoparticles. Movement of magnetite nanoparticles attached to the polymer chain in an alternating magnetic field causes the turbulence of a solvent in the diffusion layer, which leads to an increase of the mass transfer coefficient through a membrane.
