SYNTHESIS OF GO/Fe3O4 HYBRID NANOMATERIALS ORIENTED TO THE APPLICATION OF HEAVY METAL REMOVAL IN POLLUTED WATER

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.
