In the presence of a mixture of organic dyes, it exhibits excellent photocatalytic activity comparable to the destruction of individual dyes. In the field of industrial wastewater effluent treatment for environmental protection, it can be anticipated that ZnSFe2O4 is a viable photocatalyst. Additionally, ZnSFe2O4 NPs were chosen for their antibacterial efficacy against strains of gramnegative bacteria. Different microorganisms, including Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, and Staphylococcus aureus were used to test the ZnSFe2O4 NP's antibacterial activity. Jadhav et al. used urea and glycine as a combination fuel and the sol-gel auto-combustion method to produce NiFe2O4 NPs. Based on the degradation of the model component, the dye MB, the photocatalytic activity of the NPs was investigated. The obtained NPs showed high photocatalytic activity against MB dye degradation, according to the results. Gerbaldo and colleagues investigated a heterogeneous Photo-Fenton approach using CoFe2O4, H2O2, and UV light (254 nm) to remove sodium diclofenac, a common non-steroidal antiinflammatory drug. CoFe2O4 were synthesized via the Pechini process and then calcined at temperatures between 600 0 to 800 0 C. The resulting inverse spinel structure exhibited good performance in the photo-Fenton reaction. The degradation process is suggested to involve the formation of • OH radicals. Using CoFe2O4 calcined at 800°C, 86% TOC mineralization and complete degradation of sodium diclofenac were achieved. The catalyst showed minimal activity loss and low Fe leaching after three cycles. Udhaya et al. implemented an eco-friendly approach to synthesize CuFe2O4 NPs using egg white as a precursor. Notably, egg white albumin, a component of egg white, is a potential biofuel. The resulting CuFe2O4 NPs exhibit promising photocatalytic properties, as evidenced by their energy band structure. Significantly, these NPs outperform chemically synthesized CuFe2O4 NPs in degrading RhB dye under visible light, achieving an impressive degradation efficiency of 94%. To degrade the antibiotics TC and MNZ in the "MgFe2O4/H2C2O4/vis" system Qiu, et al. have identified an effective Fenton-like catalyst. This catalyst consists of metal-doped MgFe2O4 derived from saprolite laterite nickel ore. The formation of [Fe(C2O4)3] 3-complex ions due to the reaction of octahedral Fe 3+ with oxalate ions on the surface of MgFe2O4 leads to the creation of •OH radicals and ultimately enhances the catalyst's degrading activity, as per the TC degradation mechanism. The fresh catalyst's degrading performance can be maintained at over 90% even after five cycles, demonstrating its great cycling stability and applicability. The MFe2O4 nano ferrites (M = Co, Ni, and Zn) were created by Dehghani et al. The ability of spinel-type NPs to adsorb Bromo Phenol Red (BPR) dye from aqueous solutions. The outcomes demonstrated that NiFe2O4 had the greatest BPR adsorption capacity. Both the Freundlich isotherm equation and the Langmuir equation were employed to analyze adsorption behaviour. The NiFe2O4 nano spinel is a highly promising candidate for the adsorption of triphenylmethane dyes derived from wastewater. Mohammed A. et al. determined whether CoFe2O4 NPs were suitable for removing chromium and other pollutants from tannery wastewater. By annealing the CoFe2O4 NPs at 300, 500, and 900 °C, the coprecipitation approach was successful in producing the desired results. The wastewater from the tannery was treated using CoFe2O4 NPs. TDS, BOD, COD, and chromium removal were each removed with 90. De la Torre and colleagues used nitrate salts of cobalt, copper, and iron as precursors to synthesize cobalt and copper ferrites via the precipitation method. The molar ratio of Co:Fe or Cu:Fe was maintained at 1:2, with NaOH serving as the precipitant. After 8 hours of agitation, the CoFe2O4 soaked on activated carbon achieved 98% cyanide oxidation and could be recycled five times with an 18% reduction in catalytic activity. Iron dissolved more readily in CoFe2O4 compared to cobalt, while the dissolution rate of copper was higher in CuFe2O4. These results suggest that ferrite and activated carbon composites are promising alternatives for cyanide treatment in mining effluents. Frolova et al. used the co-precipitation approach and low-temperature contact nonequilibrium plasma treatment to synthesize nanocrystalline powder of CoxFe3xO4 spinel ferrite. The objective of the research was to investigate the impact of cobalt ferrite composition on the rate of the photocatalytic breakdown reaction of 4nitrophenol (4-NP) under UV light. The findings indicate that the photocatalytic activity in the breakdown process of 4-NP diminishes with increasing. Tatarchuk et al. to make CoFe2O4 Fenton catalysts. Crystallites in the samples that were annealed at 400 and 600 °C measured 16 and 18 nm, respectively. The catalyst for the oxidation of caffeine and the breakdown of H2O2 that demonstrated the greatest improvement in catalytic activity was CoFe2O4 which had been annealed at 400 °C. The rate of caffeine breakdown increased by 85% as a result of electromagnetic heating, which more than doubled the catalytic reaction rate. CoFe2O4 heated by an electromagnetic field can act as a controlled catalyst in the water purification process. Wang and colleagues synthesized MnFe2O4 nanospheres using a solvothermal process, with oleic acid employed for hydrophobic modification. The resulting MnFe2O4 nanospheres exhibited superparamagnetic properties, high saturation magnetization, a rough surface, and a well-defined mesostructure. These unique features make the MnFe2O4 nanospheres suitable for integration into magnetorheological (MR) fluids and efficient oil removal. Using magnetic CuFe2O4, CoFe2O4, and NiFe2O4 material systems, the harmful nitro compounds (4-NP, 2,4-dinitrophenol, and 2,4,6trinitrophenol) were eliminated by Ramu, A. G., et al. The hydrothermal approach was used to create the metal ferrites, and the calcination procedure is shown in Figure . The obtained results support the idea that a material system based on CuFe2O4 NPs can be one of the potential catalysts for the process of removing nitro compounds. Table .
