Spinel Nanoferrites: Adsorption and Photocatalysis of Emerging Pollutants

In recent years, scientists have been interested in spinel ferrite-based nanomaterials because of their exceptional characteristics, such as their high saturation magnetisation (Ms ), excellent chemical stabilities, and huge surface-to-volume ratios. Spinel nanoferrites for wastewater clean-up are the subject of this chapter, which goes into great depth. Spinel ferrite has been discussed in detail, along with some of its key features. Moreover, the synthesis method and structural and magnetic characteristics of spinel ferrites are also reviewed in this chapter. There has also been a discussion of conventional wastewater treatment methods and their limitations in handling different organic and inorganic pollutants. It is possible to remove inorganic and organic pollutants from wastewater using adsorption and photocatalysis therefore, in view of this, these methods are addressed in detail. The importance of spinel ferrite nanoparticles in pollutant degradation of wastewater and its recovery has been explored. Additionally, it has been discussed how adsorption and photocatalysis can improve the efficacy of currently used conventional wastewater treatment techniques. Towards the end, the future scope of spinel nanoferrites for wastewater treatment is discussed.
