Abstract：
With outstanding advantages of high surface area, fast adsorption rate and easy separation under an external magnet, ferrite magnetic nanomaterials has become a research hotspot in wastewater treatment. However, its practical application is limited due to the low adsorption efficiency. In order to solve this problem, ferrite have been combined with organic polymers or inorganic minerals in many studies. The preparation process of ferrite composite was introduced, and the research progress in the application of ferrite magnetic composites in the adsorption of anionic pollutants was reviewed. Finally, the potential research and application direction of this material in the future were prospected.
