▎ 摘　　要

NOVELTY - Preparing graphene-ferrite three-dimensional structure involves performing reaction with 0.01-1 g of graphene powder with zinc sulfate, ferrous sulfate, oxalic acid taken in mass ratio of 1:2:1:10. The mixed solution is transferred to a hydrothermal polytetrafluoroethylene autoclave and placed in an oven reaction. After completion of the reaction, the prodcut is filtered under suction, then washed and dried. The dried powdered sample is placed in muffle furnace and calcined at 300-800 degrees C for 2-8 hours. USE - Graphene-ferrite three-dimensional structure used for absorbing dye. ADVANTAGE - The graphene-ferrite three-dimensional structure has large surface area ratio with novel appearance and showsw good dye absorbing performance.
