▎ 摘　　要

NOVELTY - Preparation of oxydiene triamine modified magnetic graphene oxide adsorbent comprises adding graphene oxide to deionized water, and uniformly dispersing to obtain first solution; dissolving ferrous chloride tetrahydrate and ferric chloride hexahydrate in deionized water to second solution; and slowly adding second solution to first solution, stirring, adding ammonia water, adjusting pH, and stirring at 70-90 degrees C for 3-5 hours. USE - Method for preparing oxydiene triamine modified magnetic graphene oxide adsorbent used for absorbing and removing heavy metal ion in wastewater. ADVANTAGE - The adsorbent has high adsorption of heavy metal ions, and easy separation and recovery from waste water.
