▎ 摘　　要

NOVELTY - Removal of heavy metal hexavalent chromium in water based on weak magnetic field comprises adding graphene oxide-loaded nano-zero-valent iron composite material to water containing hexavalent chromium, placing in non-uniform weak magnetic field, stirring solution, fully absorbing, completely reacting, and filtering using aqueous filter. USE - The method is for removal of heavy metal hexavalent chromium in water based on weak magnetic field. ADVANTAGE - The method is simple, has high reaction activity, high removal efficiency, good circulation effect and wide pH range, and solves problems on large material dosage, high cost and slow reaction rate.
