The Synthesis and Characterization of the Graphene Oxide-Polyamine Composites using for the Recovery of Heavy Metal Ions

摘要

Graphene oxide - polyamine composites have been synthesized which have metal ion capacities as high as 97.94% for cadmium ions removed from aqueous solutions. The chemical structure of obtained graphene oxide - polyamine composites was confirmed by FT-IR, XRD and SEM. The results revealed that these composites can effectively extract heavy metal ions from waste water. Using these composites the concentration of heavy metal ions is reduced to below allowable discharge limits and the recovery of heavy metal ions from waste water was realized.
