▎ 摘　　要

NOVELTY - Adsorption of colloidal graphene oxide is prepared by taking natural flake graphite as raw material, preparing 0.1-2.0 mg/mL colloidal graphene oxide, loading in dialysis bags, sealing, placing in aqueous heavy metal ion solution, sonicating, adsorbing, adding greater than or equal to 0.2 M acidic solution, sonicating, desorbing heavy metal ions from graphene oxide, and recovering colloidal graphene oxide. USE - Adsorption of colloidal graphene oxide. ADVANTAGE - The method is fast and environment-friendly.
