▎ 摘　　要

NOVELTY - Preparation of magnetic graphene oxide sorbent material involves dissolving chitosan in acetic acid solution, adding ferric chloride hexahydrate and ferrous chloride tetrahydrate, dissolving in absolute ethanol under nitrogen gas, reacting at 80-90 degrees C for 5.5-6.5 hours and performing xanthation reaction and amidation reaction, washing and drying. USE - Method for preparing magnetic graphene oxide sorbent material used for copper ion adsorption. ADVANTAGE - The magnetic graphene oxide sorbent material is lightweight, and has high adsorption efficiency.
