“…Its unique magnetic property (ferromagnetism) has been well explored in different applications including biosensors, magnetic storage devices, magnetic resonance imaging and targeted drug delivery. Magnetites have also been utilized as nano-fillers to improve the properties of packaging films, however there are only a few of reports of this application [1]. Their size, surface properties and shape vary based on the method of synthesis and intended application.…”

In this study, magnetite nanoparticles were successfully synthesized using Calotropis procera aqueous leaf extract. The effect of the whole extract and some of its phytochemicals on the particle size distribution was determined using Dynamic light scattering (DLS) while other characterizations such as UV–vis spectrophotometry, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) spectroscopy and Scanning electron microscopy (SEM) were carried out. The antimicrobial activity against selected microorganisms was also studied using the agar well diffusion method. The leaf extract showed the presence of phenols, flavonoids, saponins, alkaloids and tannins. The magnetite nanoparticle synthesized using the leaf extract (Calotropis procera/Fe3O4) had an average particle size of 11.1nm with a PDI of 0.142 while the phenolic, flavonoid and saponin extracts of Calotropis procera leafs produced magnetites with average particle sizes of 62.83nm, 68.02nm and 134nm respectively. The UV-vis spectra displayed the characteristic plasmon resonance peak at 420nm, the FTIR plots highlighted important functional groups including peaks between 600cm-1 and 400cm-1 confirming the formation of iron oxide while the SEM micrographs showed the nanoparticles were mainly irregular in shape with areas of agglomeration. Calotropis procera/Fe3O4 displayed significant anti-microbial activity against Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumonia, Aspergillus niger and Fusarium oxysporum while no activity was recorded against Escherichia coli. The study indicated that Calotropis procera leaf extract was suitable for the green synthesis of magnetite with properties that suggest that it could be potentially applied as antimicrobial nanofillers.

“…Ferrogels are complex that used in biomedical as magneto sensitive transformers (Kurlyandskaya et al, 2017). Ferrogel is prepared by two different matters a as example magnetic nanomaterials filler and hydrogel polymer (Hidayat et al, 2019). More research used different types of polymer as support in ferrogel of synthesis such as PVA (Sunaryono et al, 2018), polyacrylamide (Safronov et al, 2018), gelatin (Wisotzki et al, 2016), (PVP/PVA) polymers do as aid materials in ferromagnetic gel structure.…”

he present research work has been carried out to assess the efficiency of nanocomposite bentonite/FeXOy, coated by polyvinyl alcohol (PVP/poviden PVP), in the absorption of cation pollutants. Chemical treatment was proved by using nanocomposite bentonite/FexOy coated by polyvinyl alcohol (PVA/povidone PVP). Purified local bentonite in nano-sized model was synthesized by co-precipitation process. X-ray diffraction analysis (XRD) and other techniques have been used for the characterization of the prepared materials. The mean diameter of nanocomposite material sizes was around 31.5 nm. The presence of functional groups of polymer around a core of nano-FexOy has been confirmed. Magnetic measurements have been made with a vibrating sample magnetometer (VSM), which demonstrate the superparamagnetic nature of the nanocomposite with higher saturation magnetization, but when bentonite merged with nanomagnetite new data have been given showing relatively lower saturation magnetization than before. The purpose of work is to explain the valuability of bentonite/PVA-PVP/FeXOy for adsorption of cations pollutant and its efficiency by graft polymerization of modified bentonite IONPs. The removal efficiency of five heavy metals Co, Cr, Cu, Fe, and Mn was 83.40%, 84.66%, 86.50%, 90.06% and 85.66%, respectively. Optimal conditions of nanocomposite bentonite/PVA-PVP/FeXOy experiment were nanocomposite dosage at 7.5 g/L; contact time at 30 min; temperature at 50 o C and pH at 6.0.
