▎ 摘  要

NOVELTY - Preparing a hydrophilic graphene/spinel type ferrite composite material involves adjusting the pH value of the graphene oxide aqueous solution to acidity, adding a certain quality of modifier, ultrasonically disperse, and then hold it at 60 degrees C for 1 to 4 hours, after adjusting the pH value of the mixture to neutral, adding a certain quality of iron-containing reagent, and ultrasonically disperse at 85-95 degrees C at constant temperature, dropping precipitation agent to form crystalline product and keeping constant temperature for 3-5 hours, after dropping. A magnet is used to separate the crystalline product in solid and liquid, washed it repeatedly with a solvent, and dried it at 60 degrees C for 12 hours to obtain a hydrophilic graphene/spinel ferrite composite material. USE - Method for preparing hydrophilic graphene/spinel type ferrite composite material. ADVANTAGE - The method is simple process and easy control with simple process and easy control, so as to obtain a heterogeneous Fenton catalyst with high catalytic activity and magnetic separation and recovery. The water contact angle of the graphene/spinel ferrite composite material is only 15.02 degrees , showing excellent hydrophilicity.
