Despite the efficiency of ZnO nanoparticle (NPs) composite adsorbents in the adsorption of various pollutants, there is presently no report on the combo of Znonps with biomass for adsorption. Besides, there is a dearth of information on the biosorption of celestine blue (ceB), a dye used in the nuclear and textile industry. in this study, biogenic-chemically mediated synthesis of a composite (Zno@Acp) was prepared by the impregnation of Znonps onto Ananas comosus waste (Acp) for the adsorption of ceB. the SeM, eDX, ftiR, XRD, Bet, and tGA characterizations showed the successful presence of Znonps on the biomass to form a nanocomposite. the uptake of ceB was enhanced by the incorporation of ZnONPs on ACP. A faster CEB adsorption onto ZnO@ACP (120 min) compared to ACP (160 min) was observed. The Langmuir (R 2 > 0.9898) and pseudo-second-order (R 2 > 0.9518) models were most appropriate in the description of the adsorption process. the impregnation of Znonps onto the biomass enhanced the spontaneity of the process and displayed endothermic characteristics. High CEB desorption of 81.3% from the dye loaded ZnO@ACP as well as efficient reusability showed the efficacy of the prepared nanocomposite for CEB adsorption. The pollution of environmental water from industrial effluents contaminated with industrial by-products is on the rise. This is attributed to the rapid growth of industries, hence the increase in industrial activities across the globe. About 700,000 tons of over 100,000 commercial dyes are produced annually in industries, which makes dye the most common water pollutant 1. Most dyes are used in the textile and paper industries and are frequently encountered in the effluents subsequently released into the environment 2,3. These dyes present in the environmental waters can be carcinogenic, mutagenic, and result in chronic illnesses in humans and aquatic organisms 3,4. Apart from that, they reflect or absorb light entering the water thus hindering the photosynthetic activity of aquatic plants 1. Therefore, the removal of dyes from wastewater is necessary to abate their harmful effects on the ecosystem 5,6. Most dye removal studies have focused on the removal of dyes such as methylene blue, congo red, malachite green, rhodamine B, methyl orange, methyl violet, reactive black, basic blue, acid yellow, brilliant green, and crystal violet 7,8. However, research on the removal of celestine blue (CEB) is rare despite the wide use of CEB in the nuclear and textile industries. Therefore, the removal of CEB from wastewater is important. Several techniques have been harnessed for the remediation of dye-polluted water, such as filtration, coagulation, oxidation, precipitation, reduction, photocatalytic degradation, solvent extraction, and adsorption 9. The adsorption technique is the most efficient and adsorption on bio-waste (biosorption) is promising due to the simplicity, low cost, degradability, reusability, and efficiency 10. Hence, the use of several bio-waste for the biosorption of dyes has received much attention,...

Purpose: In this study, leaf/flower aqueous extract of medicinal plant species Mentha pulegium was used to synthesize ZnO and CuO nanoparticles (NPs) as a cost-effective, one-step, and eco-friendly method. Methods: Physicochemical properties of both metal oxide NPs (MONPs) were determined by UV-Vis spectroscopy, X-Ray Diffraction (XRD), Fourier-Transform Infra-Red (FTIR) spectroscopy, Scanning Electron Microscope (SEM) and Energy Dispersive X-ray (EDX) techniques. Results: Phytofabricated ZnONPs and CuNPs illustrated 65.02±7.55 and 26.92±4.7 nm with antibacterial activities against antibiotic-resistant Escherichia coli and Staphylococcus aureus. Higher antibacterial activities were observed for CuONPs compared with ZnONPs. Conclusion: Large surface area and more reactivity resulted from smaller size as well as higher production of reactive oxygen species (ROS) were considered to antibacterial efficiency of CuONPs against antibiotic-resistant E. coli and S. aureus.

“…As a result, particles with a size of 20 -40 nm were obtained, which can be used in cosmetics and pharmaceuticals. Vidovix et al [25] extracted copper oxide via "green" synthesis method, with the addition of Punica pomegranate leaf extract. Such a nanomaterial with a spherical shape and a particle size of about 20 nm was subsequently used for adsorption of the methylene blue dye.…”

In this paper, the synthesis of spinel magnesium ferrite (MgFe2O4) nanoparticles is reported, along with its structural, magnetic and hyperthermic properties, which ensure them being effectively used in various fields. Firstly, magnesium ferrite was synthesized via sol-gel auto-combustion method, using honey as the reducing agent. The crystallite size was calculated via the Scherrer method, the modified Scherrer method, the Williamson-Hall method, and the size-strain plot (SSP) method. X-ray analysis was used to confirm the structure of the spinel. For morphological study of ferrite nanoparticles, scanning electron microscopy (SEM) was used. Finally, hyperthermic properties of magnesium ferrite were analyzed for potential usage in medicine. According to these results, spinel magnesium ferrite (MgFe2O4) nanoparticles proved to be suitable for destruction of cancer cells, as they can be heated to the desired temperature, which will increase the sensitivity of those cells.
