Fe3O4-embedded graphene oxide was developed as a magnetic adsorbent for removal of methylene blue from aqueous solution. Fe3O4 nanoparticles were embedded on the surface of the as-prepared graphene oxide via a co-precipitation procedure with cheap and environmentally friendly iron salts. The weight percentage of graphene oxide was estimated by calcination to be about 18.5 %. In the aqueous solution of methylene blue at 20 A degrees C, the adsorption data agreed well with the Langmuir adsorption model with a maximum adsorption capacity of 246 mg/g and a Langmuir adsorption equilibrium constant ...
