Abstract
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.
