Tóm tắt
SYNTHESIS AND APPLICATION OF MAGNETIC COMPOSITE NANOMATERIAL BASED ON GRAPHENE OXIDE TO REMOVE METHYLENE BLUE AND CONGO RED IN WATER
In this study, graphene oxide was prepared by the modified Hummers method, and then iron oxide nanoparticles were deposited on the surface of graphene oxide by hydrothermal method. After synthesis, these materials were characterized via a number of physical methods: X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM) and scanning electron microscopy (SEM/EDX). The results show that the iron oxide particles were synthesized with nano-size, and the material after modified by graphene oxide still retains the magnetism. These materials continue to be evaluated the for removing methylene blue and Congo red in the water. The results show that the synthesized composite materials can selectively adsorb methylene blue and Congo red, thereby showing the potential application of magnetic composite materials in the field of wastewater treatment.
