Abstract
The paper presents the synthesis of GO/Fe3O4 hybrid nanomaterials by the co-precipitation method. The structural, morphological and physicochemical properties of hybrid nanomaterials were characterized by XRD, SEM, FTIR and Raman methods. The results showed that Fe3O4 nanoparticles with small size, porosity and good bonding with graphene sheets of GO. As(III) adsorption efficiency of GO/ Fe3O4 was up to 95.24% and the maximum adsorption capacity could reach up to 112.2 mg/g. Experimental data fit well with Langmuir model (R2 = 0.9983). This is considered a material with great potential in treating heavy-metal containing wastewater in water environment.
