Recent studies highlight a growing interest in porous magnetic materials for water pollutant detoxification. These materials are effective due to their enhanced efficiency and ease of separation post-treatment. Reddy et al. developed a three-dimensional porous NiFe2O4 adsorbent (PNA) with notable magnetic properties, used to detoxify an aqueous Pb (II) solution. The PNA was synthesized using chitosan as a precursor through a sol-gel process. The PNA's surface appearance as seen in SEM scans revealed its three-dimensional porous structure, with many interconnected pores. The NiFe2O4 adsorbent with a 3D porous structure shows remarkable adsorption characteristics for the elimination of Pb (II) from water-based solutions. It takes less than 60 minutes to achieve equilibrium due to the rapid adsorption rate. Lastly, it was shown that the adsorbent PNA has exceptional capability for handling wastewater containing Pb (II). Sharma et al. synthesized spinel ferrites with the formula MFe2O4 (where M represents Ni, Cu, Zn, and Co) to explore their effectiveness in degrading the reactive azo dye RB5, a model pollutant, through Fenton and photo-Fenton systems. CuFe2O4 demonstrated high efficiency due to the involvement of Cu 2+ ions in Fenton's reaction, leading to the production of more hydroxyl radicals. All the catalysts remained stable, magnetically separable, and recyclable even after four cycles, making them promising materials for wastewater treatment in the textile industry. In the current study, SnFe2O4
