“…At the same time, with the decrease of the Fe 3 O 4 content, the saturation magnetization of the heteroplasmon nanoparticles also gradually reduced, and the saturation magnetization was the largest of 51.4 emu g −1 when the volume of absolute alcohol was 20 ml (figure 6(b)). With the increase of absolute alcohol volume, the dispersion of α-Fe 2 O 3 nanoparticles in absolute alcohol increased, the area in contact with the atmosphere also increased, and the oxidation enhanced during the combustion process [26]. When the volume of absolute alcohol increased, the combustion and oxidation time were belonged, which caused the decreased of Fe 3 O 4 content.…”

In this work, a feasible and facile hydrolysis-combustion-calcination process of ferric nitrate for the preparation of magnetic α-Fe2O3/Fe3O4 heteroplasmon nanoparticles was represented. The influences of hydrolysis time, hydrolysis temperature, Fe3+ concentration, anhydrous ethanol volume, calcination time, and calcination temperature on the properties of α-Fe2O3/Fe3O4 heteroplasmon nanoparticles were investigated. According to a series of characterization analysis, the optimal preparation conditions were confirmed: 0.05 M Fe(NO3)3·9H2O was hydrolyzed at 90 ℃ for 8 h, and then the precursor was calcined at 200 ℃ for 2 h with 20 mL anhydrous ethanol. While, the morphology of α-Fe2O3/Fe3O4 heteroplasmon were spherical structures with the average particle size of about 46 nm, and their saturation magnetization was 54 emu g-1. The α-Fe2O3/Fe3O4 heteroplasmon nanoparticles possessed controllable magnetic properties and a more stable state, which suggested promising applications.

A novel nitrate solution combustion process for formation of magnetic Mg0.5Ni0.5Fe2O4 nanoparticles was introduced, and XRD, VSM, SEM, TEM, and BET techniques were employed to characterize the nanoparticles. For Mg0.5Ni0.5Fe2O4 nanoparticles prepared at 400 °C for 2 h with 20 mL absolute ethanol, the average size and the saturation magnetization were approximately 22 nm and 8.1 A·m2/kg, respectively. Mg0.5Ni0.5Fe2O4 nanomaterials were subjected to reactive red 2BF adsorption, and the adsorption performances were investigated. The results revealed that the experimental data fit the Temkin isotherm model and the pseudo-second-order kinetics model, suggesting that the RR-2BF adsorption process was a monolayer-multilayer-associated chemisorption mechanism. The effects of pH on the adsorption capacity and cycle capacity of the magnetic Mg0.5Ni0.5Fe2O4 nanoparticles for the adsorption of reactive red 2BF were revealed.

“…In addition, the material retained 97.6% adsorption capacity till three cycles, and after that it decreased significantly. In another research, Li et al (2021) found that nickel-magnesium ferrite (Ni 0.9 Mg 0.1 Fe 2 O 4 ) can adsorb maximum 306.4 mg/g methylene blue when initial concentration was 900 mg/l at pH 5. The material can adsorb more than 90% methylene blue in three adsorption desorption cycles, but adsorption capacity reduced significantly (60% in seven cycles) owing to material loss and pore collapse in further cycles.…”

Nanoadsorbents having large specific surface area, high pore volume with tunable pore size, affordability and easy magnetic separation gained much popularity in recent time. Iron-based nanoadsorbents showed higher adsorption capacity for different pollutant removal from water among other periodic elements. Spinel ferrite nanomaterials among iron-bearing adsorbent class performed better than single iron oxide and hydroxides due to their large surface area, mesoporous pore, high pore volume and stability. This work aimed at focusing on water treatment using magnesium ferrite (MgFe 2 O 4 ) nanomaterials. Synthesis routes, properties and pollutant adsorption were critically investigated to explore the performance of magnesium ferrite in water treatment. Structural and surface properties were greatly affected by the factors involved in different synthesis routes and iron and magnesium ratio. Complete removal of pollutants through adsorption was achieved using magnesium ferrite. Pollutant adsorption capacity of MgFe 2 O 4 and its modified forms was found several folds higher than Fe 2 O 3 and Fe 3 O 4 nanomaterials. In addition, MgFe 2 O 4 showed strong stability in water than other pure iron oxide and hydroxide. Modification with graphene oxide, activated carbon, biochar and silica was demonstrated to be beneficial for enhanced adsorption capacity. Complex formation was suggested as a dominant mechanism for pollutant adsorption. These nanomaterials could be a viable and competitive adsorbent for diverse pollutant removal from water.
