A novel magnetic nanoadsorbent has been synthesized by the covalent immobilization of thiosalicylhydrazide on surface Fe3O4 nanoparticles. Size, structure, property, and porosity prepared nanoparticles (MNPs) were studied scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), atomic force (AFM), transmission (TEM), vibrating sample magnetometer (VSM), Fourier transform infrared (FT-IR), diffraction (XRD) analysis. The ability MNPs for removing heavy metals ions (Pb2+,...
The aim of this work was to develop a superadsorbent for the removal Hg2+ ions from aqueous solutions. In regard, porous covalent triazine ring-based nanoneedle synthesized through facile hydrothermal method. structure and morphology adsorbent were characterized by different techniques. structural stability examined under temperatures pH conditions. maximum adsorption capacity prepared organic framework is 1826 mg g–1 removing at ambient temperature an optimum 5. Different linear nonlinear...
Abstract In this work, the preparation and characterization of glutaraldehyde-crosslinked electrospun nanofibers chitosan/poly(vinyl alcohol) (GCCPN) as a new adsorbent for tetracycline (TC) is reported. Electrospun nanofibers (PVA) were prepared by employing 75:25 volumetric ratio chitosan:PVA, voltage 30 kV, collection distance 10 cm, injection flow rate 2 mL/h. Then, crosslinked via applying glutaraldehyde on them 3 h at 40 °C. The characterized using scanning electron microscopy, Fourier...
Magnetic nanoparticles of iron oxide (Fe 3 O 4 NPs) were prepared using a biosynthetic method to investigate their potential use as an adsorbent for adsorption Pb(II) and Cd(II) from the aqueous solution. The present study first time used magnetite leaf extract Portulaca oleracea removal metal ions. Characterizations Fe NPs (PO‐Fe MNPs) achieved by X‐ray diffraction (XRD), field emission scanning electron microscope (FESEM), energy‐dispersive spectroscopy (EDX), transmittance microscopy...
In this work, we report ultrasonic-assisted synthesis of layered double hydroxides (LDHs) containing biodegradable amino acid derivative, N,N′-(pyromellitoyl)-bis-l-isoleucine diacid, and their application for removal cyanide ions from industrial wastes. The structure the modified Mg–Al LDHs was studied using transmission electron microscopy (TEM), field-emission scanning (FE-SEM), FT-IR spectroscopy, X-ray diffraction (XRD) techniques. ability prepared adsorption aqueous solutions examined,...
