Synthesis of iron oxide nanoparticles has attracted increasing interest due to their importance in biomedical and technological applications. To investigate the ability Juglans regia (J. regia) green husk extract size control, they were synthesized through co-precipitation method with J. without it. For both tests, other experimental conditions same. According High-resolution transmission electron microscopy, mean diameter standard deviation regia/iron using 12.60 ± 2.87 5.77 1.66 nm...
Fe3O4/talc nanocomposite was used for removal of Cu(II), Ni(II), and Pb(II) ions from aqueous solutions. Experiments were designed by response surface methodology (RSM) a quadratic model to predict the variables. The adsorption parameters such as adsorbent dosage, time, initial ion concentration independent variables their effects on heavy metal investigated. Analysis variance incorporated judge adequacy models. Optimal conditions with 100, 92 270 mg/L, 120 s time 0.12 g amount resulted in...
The aim of this study was to prepare zeolite/iron (III) oxide nanocomposites (zeolite/Fe2O3-NCs) as a smart fertilizer improve crop yield and soil productivity.Zeolite/Fe2O3-NCs were successfully produced by loading Fe2O3-NPs onto the zeolite surface using quick green precipitation method. production zeolite/Fe2O3 performed under mild condition environmentally friendly raw materials new chemistry product characterized several techniques such near far Fourier-transform infrared spectroscopy...
Small sized magnetite iron oxide nanoparticles (Fe3O4-NPs) with were successfully synthesized on the surface of rice straw using quick precipitation method in absence any heat treatment. Ferric chloride (FeCl3·6H2O), ferrous (FeCl2·4H2O), sodium hydroxide (NaOH) and urea (CH4N2O) used as Fe3O4-NPs precursors, reducing agent stabilizer, respectively. The fibers dispersed deionized water, then was added to suspension, after that ferric this mixture stirred. After absorption ions layer fibers,...
Rice straw/magnetic nanocomposites (RS/Fe3O4-NCs) were prepared via co-precipitation method for removal of Pb(II) and Cu(II) from aqueous solutions. Response surface methodology (RSM) was utilized to find the optimum conditions ions. The effects three independent variables including initial ion concentration, time, adsorbent dosage investigated on maximum adsorption Pb (II) Cu (II). obtained (100 60 mg/L) (41.96 59.35 s) time 0.13 g both ions, respectively. efficiencies 96.25% 75.54%, In...
Novel mixed matrix membranes were prepared from polysulfone (PSf), talc and Fe3O4–talc nanocomposite by phase inversion technique. PSf/Fe3O4–talc showed higher lead nickel rejections compared to PSf/talc membranes, which reaches 99.4 96.2% for ions, respectively, at feed pH 5 lower 3.5 2. Higher surface area in than could be considered as a main reason of heavy metals removal membranes. The enhances with the increase content 7 9 wt.% because numbers vacant sites membrane morphology available...
Iron oxide nanoparticles (Fe 3 O 4 ‐NPs) were synthesized using chemical coprecipitation method. Fe ‐NPs are located in interlamellar space and external surfaces of montmorillonite (MMT) as a solid supported at room temperature. The size magnetite could be controlled by varying the amount NaOH reducing agent medium. changed from 1.24 nm to 2.85 average diameter was 12.88 8.24 nm. characterized some instruments such transmission electron microscopy, powder X‐ray diffraction, energy dispersive...
