Preparation and dye adsorbing properties of Fe 3O4 carbon/graphene oxide composites.
Abstract
Fe3O4@carbon/graphene oxide (Fe3O4@c/go) composites were synthesized by hydrothermal method and characterized by X-ray diffraction, transmission e Lectron microscopy, vibrating sample magnetometer. And their dye
Adsorbing properties were investigated. The results indicated that the Fe3O4 Nanoparticles were uniformly anchored on go sheets. The saturated adsorption capacities towards rhodamine B (RhB) of the composites increased with the increase of Go content, initial RhB concentration and Adsorbing temperature. And the higher go content in The composite was, the quicker the absorbing Rate was. The saturated adsorption capacity of The composite reached a maximum value When the PH value is 7. For the composite prepared at 0.8 Of the mass ratio of Go To Fe 3O4, The saturated adsorption capacity reached 303.4mg/g at 1000mg/l of initial RhB concentration.
