This paper reports the successful synthesis of spinel‐type CuFe 2 O 4 ferrite nanoparticles with an average particle size 24 nm, produced using citrate sol–gel autocombustion method. The structure synthesized material was analyzed through x‐ray diffraction (XRD) and further supported by Raman FT‐IR spectroscopy. analysis confirmed that formed a spinel Fd3m space group. Valence states energy levels elements were examined photoelectron spectroscopy (XPS). Surface morphology studied scanning electron microscopy (SEM), coupled elemental analysis. magnetic properties investigated vibrating sample magnetometer (VSM). Magnetization measurements revealed exhibited characteristic parameters copper ferrite, saturation magnetization (Ms) 23.10 emu/g, coercivity Hc 415 Oe, remnant (Mr) 12.80 emu/g. These enable efficient separation from aqueous solutions, thereby enhancing process efficiency minimizing catalyst loss during photocatalytic applications. Optical spectrophotometry, revealing optical band gap 1.85 eV, which demonstrates potential for activity under visible light. effectively degraded dyes such as methylene blue (MB), malachite green (MG), Safranine (S), Congo Red (CR), Rhodamine B (RhB) within 180 min, highlighting its practical application potential. study identified hydroxyl radicals (·OH), generated H decomposition light irradiation, played critical role in photo‐Fenton reaction. A proposed mechanism involves excitation light, facilitating transfer leads to generation ·OH radicals, degrade dye molecules. Among tested dyes, CR highest degradation percentage rate constant 0.033 min⁻ 1 followed pseudo‐first‐order kinetic model. effect hydrogen peroxide concentration on also evaluated.

Abstract BACKGROUND Hybrid iron and cobalt metal oxide nanoparticles are well known; however, not optimized in terms of size stability. We engineered these hybrid using the co‐precipitation method characterized them by various techniques, which then used for effective adsorption removal malachite green (MG) dye. RESULTS The ideal conditions synthesis determined to be 50:50 ratio Fe 2 O 3 CoO, pH 11, temperature range 40 °C–60 °C, reactant addition time 20 min. These nanoadsorbents effectively eliminated MG dye from aqueous solutions. Factors such as initial concentration, medium, contact time, temperature, nanoadsorbent dose were achieve a maximum efficiency 96.9%. Non‐linear fitting data indicates that both Langmuir Freundlich models provided best fit, suggesting presence monolayer multilayer on nanoparticles. kinetics better controlled intraparticle diffusion (IPD) phenomenon. onto was confirmed endothermic, with negative ΔG positive ΔH values. synthetic also positively impacted enhanced exhibited ferromagnetic behavior compared superparamagnetic reported literature, making significantly important applications. CONCLUSION findings demonstrate potential applications, implications further applications photocatalysis sensing. © 2024 Society Chemical Industry (SCI).

This study details the synthesis and application of magnetic copper ferrite (CuFe2O4) nanoparticles for efficient removal acid red 88 crystal violet dyes from aqueous solutions. Utilizing a combustion method, were synthesized with succinic malic acids as fuels, yielding samples crystallite sizes 28.54 ± 0.90 nm sample 19.79 0.75 acid. Optimum conditions found at pH 2 10 violet, contact time 80 min an adsorbent dosage 0.05 g in 100 mL solution. Under these conditions, using achieved sorptive capacities 452.49 mg/g 446.43 while reached 408.16 374.53 mg/g, respectively. Both adsorption processes followed pseudo-second-order kinetic model aligned Langmuir isotherm. Thermodynamic analysis confirmed process exothermic spontaneous. Practical trials demonstrated efficiencies above 95% both real wastewater samples, underscoring method's practical potential water purification applications.
