▎ 摘  要

NOVELTY - Preparing magnetic nano composite oil absorbent material comprises (1) adding oxidized graphene, ferrous sulfate heptahydrate and ferric chloride hexahydrate, adding sodium hydroxide solution to react to obtain magnetic graphene oxide/ iron(II,III) oxide particles, (2) using step (1) to obtain the magnetic oxide graphene/ iron(II,III) oxide particles, mixing with tetramethyl ammoniumhydroxide solution, (3) using the mixed solution obtained in the step (2), separating out after hydrophilic treatment of magnetic oxide graphene/ iron(II,III) oxide particles and adding it into chitosan acetic acid aqueous solution to obtain magnetic oxide graphene/ iron(II,III) oxide particles-of chitosan acetic acid solution, (4) using step (3), magnetic oxide graphene/ iron(II,III) oxide particles-of chitosan acetic acid solution to the sodium stearate in the solution to obtain the finished product. USE - The method is useful for preparing magnetic nano composite oil absorbent material. ADVANTAGE - The material: is convenient for recycling oil-absorbing material.
