Magnetic graphene oxides as highly effective adsorbents for rapid removal of a cationic dye rhodamine B from aqueous solutions

A functional hybrid of Fe3O4 magnetic nanoparticles-graphene oxide (MNPs-GO) has been chemically synthesized, and its ability to separate the cationic dye rhodamine (RhB) from aqueous solutions was investigated. The MNPs-GO nanoadsorbent exhibited excellent capability to remove RhB from real water samples.
