Adsorption and removal of Congo red dye from aqueous solution by using nano-Fe3O4
In this paper,nano-Fe3O4 as sorbent was used to remove Congo red dye from aqueous solution,in order to investigate its adsorption properties.Fe3O4 nano-particles were synthesized by hydrothermal method,and were characterized by Scanning Electron Microscope (SEM),Fourier Transform Infrared Spectroscopy (FT-IR) and X-ray Powder Diffraction (XRD) to examine their size,morphology and property.The adsorption and removal of Congo red dye from aqueous solution on nano-Fe3O4 was studied in batch equilibrium experiments.These results showed an excellent adsorption capability for Congo red with a maximum adsorption capacity of 1395mg·g-1 at 20℃ and pH2.0.It indicates that Fe3O4 nano-particles can be effectively used to remove color from wastewater containing dyes.
