“…these nanoparticles are generally called transition metal oxides and have spinel structures. the magnetization of ferrite nanoparticles depends on the size, shape, surface morphology, and distribution of the crystallites [1][2][3][4]. Manganese ferrite nanoparticles show low magnetic losses and high permeability [5].…”

Post-synthesis Microwave PlasMa treatMent effect on Magnetization and MorPhology of Manganese-iron oxide nanoParticlesthe influence of microwave (MW) plasma on magnetization and morphology of sol-gel synthesized MnFe 2 O 4 ferrite nanoparticles is investigated in this study. Manganese (ii) nitrate hexahydrate, ferric (iii) nitrate nanohydrate and citric acid were used to synthesize ferrite nanoparticles via a facile sol-gel route. these ferrite nanostructures were heat-treated at 700ºC and then given MW plasma treatment for 10 min. the pristine MnFe 2 O 4 and plasma treated MnFe 2 O 4 showed almost similar structural formation with a slight increase in crystallinity on plasma treatment. however, Xrd peak intensity slightly increased after plasma treatment, reflecting better crystallinity of the nanostructures. the size of the particle increased from 35 nm to 39 nm on plasma treatment. it was challenging to deduce the surface morphology of the nanoparticles since both samples were composed of a mixture of big and small clusters. Clusters that had been treated with plasma were larger in size than pristine ones. the band gap energy of the pristine MnFe 2 O 4 sample was about 5.92 eV, which increased to 6.01 eV after treatment with MW plasma. the saturation magnetization of MnFe 2 O 4 sample was noted about 0.78 emu/g before plasma treatment and 0.68 emu/g after MW plasma treatment.

In this study, Ni-ZnFe2O4 nanoparticles were synthesized by co-precipitation technique and used to remove the chromium (Cr) metal from the industrial wastewater. The synthesized nanoparticles were characterized for their structural properties and morphology by using X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. The average particle size of synthesized nanoparticles was calculated by applying the Scherrer’s formula on the characteristic peaks of XRD patterns. The large surface area, controlled size and well-defined structure of the synthesized Ni-ZnFe2O4 nanoparticles showed remarkable results for wastewater treatment. The characterized nanoparticles were distributed into the industrial wastewater under constant stirring for 20 minutes. The nanoparticles’ suspension was subjected to UV–VIS spectrophotometry for the study of photo-catalytic behaviour of Ni-ZnFe2O4 nanoparticles. The effect of Ni-ZnFe2O4 was investigated under visible light irradiation. Zn doping in Ni-ZnFe2O4 showed remarkable effect on efficiency of Cr removal from the wastewater.
