Abstract

The invention discloses a micropore filtration-aiding type magnetic nanometer material. The micropore filtration-aiding type magnetic nanometer material is prepared from the following raw materials in parts by weight. According to the micropore filtration-aiding type magnetic nanometer material and the preparation method disclosed by the invention, magnetic nanometer ferroferric oxide granules are introduced in a compound material, and the magnetic granules are loaded on the surface of the compound material, so that the dispersibility of ferroferric oxide can be improved, and the problem that a conventional adsorbent material is difficult to separate and reclaim from a reaction system is effectively solved. According to the micropore filtration-aiding type magnetic nanometer material and the preparation method disclosed by the invention, nanometer diatomite is used as a main material, has favorable permeability, and can filter off superfine suspended substances; the nanometer diatomite is matched with scolecite, so that finished products have many micropores, and the micropore filtration-aiding type magnetic nanometer material has good applicability in the field of removing condensed ring pollutants in waste water and the like.
