This review focuses on the use of spinel ferrites in the treatment of wastewater contaminated with dyes. It highlights the potential of spinel ferrites as a costeffective, efficient, and sustainable solution. Spinel ferrites, which have the general formula AB2O4, possess unique properties such as a high surface area, porosity, magnetic characteristics, chemical stability, and corrosion resistance. These properties make them highly effective in adsorbing and degrading dye pollutants. The catalytic properties of spinel ferrites enable advanced oxidation processes, leading to the efficient degradation of organic dyes. Moreover, the magnetic nature of spinel ferrites allows for easy separation from treated water, enabling their reuse and reducing operational costs. Research has shown that spinel ferrites can effectively remove a wide range of dye contaminants from real wastewater, and their ability to be regenerated ensures their long-term applicability. Spinel ferrites are environmentally friendly and scalable for industrial applications, making them versatile in treating various sources of dye-laden wastewater, including industrial effluents and textile wastewater. Despite their promise, there are challenges that need to be addressed, such as developing cost-effective synthesis methods, optimizing operational parameters for real wastewater conditions, and ensuring long-term stability and performance in continuous systems. Combining spinel ferrites with other technologies, such as membranes and biochar, could further enhance treatment efficiency. The integration of spinel ferrites into hybrid systems and their ability to function under diverse environmental conditions make them a promising solution for future innovations in dye degradation.
