Nghiên cứu tổng hợp và khảo sát khả năng xử lý xanh methylen và đỏ Công gô trong môi trường nước của vật liệu composit từ tính oxit sắt/graphen oxit

Abstract

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.
