“…A wide variety of adsorbents like metal oxides [16], activated carbon [17,18], biomass [19,20], polymer, nanosilicates, nanoferrites, resins etc. were extensively used [21][22][23][24][25][26][27]. Polymer-based adsorbents are used worldwide for remediation of wastewater due to their high stability, porosity and large adsorption capacities [6].…”

Synthesis of iron-zirconium binary oxide fabricated ethylene diamine (IZBO-en) composite involved two step synthesis including mixed binary oxide synthesis followed by synthesis of binary oxide-ethylene diamine composite. Mixed binary oxide was synthesized by co-precipitation method using ammonia as neutralizing agent. Binary oxide based ethylene diamine composite was synthesized using sodium dodecyl sulfate and potassium persulfate as reagents in reaction. Yield of product was 88%. Characterization of the material was done using Fourier-transform infrared spectroscopy, scanning electron microscopy, and Brunauer-Emmett-Teller analysis. Surface area was found to be 54.74 m 2 g-1. The synthesized material was efficient for removal of cationic dye methylene blue which is known for its toxicological effects. Adsorption parameters like contact time, dose, interference and pH were studied. Maximum adsorption capacity was found to be 242.79 mg g-1. Kinetic data suggested the mechanism of adsorption follows pseudo-second-order rate (R 2 = 0.998) with a rate constant of 2.788 mg g-1 min-1 and follows Langmuir adsorption isotherm model (R 2 = 0.987). Thermodynamic study revealed the process to be spontaneous and feasible with large negative free energy (ΔG =-9.54 kJ mol-1). Column study shows a removal of 600 ml 2 mg L-1 with 1 g material. Desorption was achieved with 79% regeneration in acidic medium. Real wastewater from nearby textile industry was tested and found to get decolourized with the material. In conclusion, IZBO-en can be efficiently used in detoxification of cationic dyes.

“…The results reveal that lattice parameters of S4 sample is less than the those of the others, and calcination at high temperature decreases the lattice parameters of all samples. Rietveld refinement of X-ray data shows cation ions distribution in all of the planes, especially in (3 1 1) one, and the results confirm the formation of the spinel phase [19]. According to Fig.…”

“…These types of reactions reduce heat decomposition temperature and lead to better particle size distribution [14][15][16][17][18]. The presence of ferric ions in sites of A and B affects the magnetic field, and according to that, the size of the ion modifies the magnetic properties [19]. The transition of cations to other sites caused by thermal treatment and ionic substitution [20] as well as redistribution of cations or substitution of other ions may enhance or reduce the physical properties [21].…”

The purpose of studying the properties of zinc-manganese nanoferrite was to compare organic fuels that were produced in conditions created by the auto gel combustion method, using citric acid, glycine, and urea with different pH values: (citric acid = 6, glycine = 3 and urea = 0). The samples were prepared in stoichiometric ratios to gain Mn0:5Zn0:5Fe2O4, and all the samples were calcined in the same condition (500 °C and 30 minutes). It should be noted that the entire process of synthesis was photographed to analyze the effect of fuels during the combustion process. Combustion reactions were studied by simultaneous thermal analysis (STA), FT-IR spectroscopy, and X-ray diffraction (XRD), also the Rietveld method was used to determine the type and amount of crystalline phases. Magnetic properties of the samples were measured by vibration sample magnetometer (VSM), and their morphology and powder agglomeration was observed by field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). Superior magnetic properties of the sample synthesized with glycine were achieved. Urea gave the smallest particle size, while citric acid produced intermediate properties.

[5][6][7] At present, most of the studies on MnÀ Zn ferrites are concentrated on utilizing different metal ions to partially replace the tetrahedral and octahedral metal ions in the structure of MnÀ Zn ferrites.

To reveal the intrinsic mechanism of MnxZn1‐xFe2O4 (x=0.2, 0.4, 0.6, 0.8 and 1) nanoferrite with various content of Mn/Zn are prepared by hydrothermal method. The physical properties are characterized by X‐ray diffraction (XRD), Fourier transformed infrared spectrometer (FTIR), Transmission electronic microscope (TEM), Energy Dispersion Spectrum (EDS) and Vibrating Sample Magnetometer (VSM). The phase structure, lattice parameters, and magnetic properties have been investigated based on the entire cation distribution with enhancement of the Mn2+. The XRD and FTIR analysis indicate that the samples have cubic spinel ferrite structure, the lattice constant at and crystallite size D increase with enhancement of Mn content. The VSM plots demonstrate that the Mn0.6Zn0.4Fe2O4 sample has the largest saturation magnetization value (77 emu/g). These results indicate that a fine tuning of Mn2+ content can adjust the micro‐structure and magnetic properties of MnxZn1‐xFe2O4.
