▎ 摘　　要

NOVELTY - Preparing ferromagnetic carbon-based composite material comprise: (1) mixing the activated carbon with graphene oxide solution, adding chain agent to react, performing first solid-liquid separation to obtain activated carbon/graphene oxide; (2) mixing the activated carbon/graphene oxide and ferrous ion solution for dipping; obtaining precursor by the second solid-liquid separation; and (3) carrying out carbon thermal reaction to the precursor. USE - The ferromagnetic carbon-based composite material is used for processing anionic pollutant waste water and/or organic waste water (claimed). ADVANTAGE - The method pre-loads the graphene oxide on the active carbon to provide more load sites and makes the metal load more uniform; the load gamma-ferric oxide realizes magnetic separation and the magnetic gamma-ferric oxide is more stable; realizing synchronous reduction of graphene oxide by carbon thermal reaction. The material increases specific surface area; improves adsorption efficiency; can further load the non-iron metal to enhance the bacteriostasis effect; and has good removing effect to the anion or organic pollutant and has low production difficulty. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for ferromagnetic carbon-based composite material comprising activated carbon/graphene and gamma-ferric oxide.
