This paper describes the development of a procedure for Pb(II) ions removal from various water samples after magnetic solid phase extraction (MNPs) by magnetite nanoparticles (Fe3O4 NPs) modified with sodium dodecyl sulfate (SDS) and pyrrolidine-1-dithiocarboxylic acid ammonium (PDTCAA). The synthesis of Fe3O4 NPs was certified by characterization techniques including field emission scanning el...

Multifunctional hydrogels are a class of materials offering new opportunities for interfacing living organisms with machines due to their mechanical compliance, biocompatibility, and capacity be triggered by external stimuli. Here, we report dual magnetic- electric-stimuli-responsive hydrogel the disassembled reassembled up three times through reversible cross-links. This allows its use as an e...

In this work, we report the synthesis of a magnetically recoverable catalyst through immobilizing copper (II) over Fe3O4@SiO2 nanoparticles (NPs) surface [Fe3O4@SiO2-L–Cu(II)] (L = pyridine-4-carbaldehyde thiosemicarbazide). Accordingly, synthesized catalysts were determined and characterized by energy dispersive X-ray spectrometry (EDS), diffraction (XRD), Fourier transforms infrared spectrosc...

ABSTRACT. Magnetic nanoparticles (MNPs) are gaining popularity because of their small size allowing for research into the fundamentals magnetism. In wastewater treatment, adsorption methods commonly remove heavy metals, but copper (Cu+2) ion removal using magnetic (NPs) has not been investigated. this study two different modes were used to determine maximum capacity copper(II). The containing F...

objective(s): this paper describes coating of magnetite nanoparticles (mnps) with amorphous silica shells.   materials and methods: first, magnetite (fe3o4) nps were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. afterwards, coating with silica was carried out via a sol-gel approach in which the electrostati...

As the main component of radioactive wastewater, cesium ion has seriously endangered environment and human health. Prussian blue nanoparticles (PB NPs) are used as adsorbents for purification cesium-containing wastewater because their ability to selectively adsorb ions. In this work, novel magnetic nanospheres (MPBNs) were developed from polylactic acid a carrier, loaded with Fe3O4 (Fe3O4 insid...

Calotropis procera (Aiton) W.T.Aiton presents high levels of medicinally important terpenes and phenolics with antiinflammatory, antimicrobial, antioxidant properties. The present study aimed to develop a suitable platform for mass production pharmacological metabolites improvement activity C. procera. Motivated by such aim, potential effects Fe3O4 nanoparticles (Fe3O4 NPs) salicylic acid (SA) ...

Catalysts play a critical role in producing most industrial chemicals and are essential to environmental remediation. Under the demands of sustainable development, environment protection, cost-related factors, it has been suggested that catalysts sufficiently separable conveniently recyclable catalysis process. Magnetite (Fe3O4) nanomaterials provide possible way achieve this goal, due their ma...
