Facile fabrication of superparamagnetic graphene/polyaniline/Fe₃O₄ nanocomposites for fast magnetic separation and efficient removal of dye.

ABSTRACT: Using graphene as adsorbent for removal of pollutants from polluted water is commonly recognized to be costly because the graphene is usually produced by a very complex process. Herein, a simple and eco-friendly method was employed to fabricate efficient superparamagnetic graphene/polyaniline/Fe₃O₄ nanocomposites for removal of dyes. The exfoliation of graphite as nanosheets and the functionalization of nanosheets with polyaniline and Fe₃O₄ nanoparticles were simultaneously achieved via a one-pot reaction process combining the intercalation polymerization of aniline and the co-precipitation of the residual Fe³⁺ and the generated Fe²⁺. The obtained graphene/polyaniline/Fe₃O₄ nanocomposites exhibited exce
