Abstract

This chapter describes aspects of the application of spinel ferrite nanoparticles (SFNPs) in the purification of water bodies and wastewater. The structural and magnetic properties of these ferrimagnetic systems are described. Several synthesis methods are illustrated, with special focus on green processes. Furthermore, the adsorption of inorganic and organic contaminants is discussed, and several recently published adsorbent/adsorbate systems are presented. The utilization of spinel ferrites in the photodegradation of organic materials is also examined. Finally, the recovery and recycling aspects of the utilization of ferrite nanoparticles in the purification of wastewater are also presented.
