Spinel ferrite nanostructures have played significant roles in the development of materials science and technology. Spinel ferrite nanostructures possess not only promising magnetic properties but also high resistivity, stability, and low eddy current losses. The recent progress in the utilization of spinel ferrite nanostructures for water remediation is reviewed with special emphasis on the adsorption, transformation, degradation, and catalytic reduction of nitroaromatics. Then, the structure–property relationships and design considerations of spinel ferrite nanostructures for catalytic applications are discussed in detail. Insights into the details of the various removal processes on the model spinel ferrite nanostructures are provided with a basic concept of nitroaromatics remediation. Subsequently, reaction kinetics and mechanisms are classified and their advantages and disadvantages are described. Lastly, challenges and future perspectives of spinel ferrite nanostructures for their practical applications are presented. With further advancement, spinel ferrites have potential to be practically utilized for a wide range of applications such as water treatment plants.

Adsorption to date is the most effective and utilized technology globally to remove several pollutants in wastewater. In this approach, many adsorbents have been synthesized, tested and used for the elimination and separation of the contaminants such as radionuclides, heavy metals, dyes and pharmaceutical compounds both at lab and industrial scale. However, there are many challenges to adsorption processes such as reducing the high cost, through means of separation of suspending adsorbents to be used again, as well as the ease to synthesize. Two methods that have shown promising results and gained significant interest is that of magnetic nanomaterials and biosorbents due to their effective, safe, eco-friendly, low cost and low-energy intensive material properties. Magnetic nanomaterials act as efficient adsorbents due to their ease of removal of contaminants from wastewater using an applied magnetic field but also their advantageous surface charge and redox activity characteristics. On the other hand, biosorbents have a synergistic effect with their efficient adsorption capacity to remove contaminants, high abundance and participation in waste minimization, helping alleviate ecological and environmental problems. This review highlights, discusses and reports on the state-of-the-art of these two promising routes to adsorption and provides indications as to what are the optimum materials for utilization and insight into their efficiency, reusability and practicality for the removal of pollutants from wastewater streams. Some of the main material focuses are zero-valent iron, iron oxides, spinel ferrites, natural and waste-based biosorbents.
