BACKGROUND In this Research, oyster shell supported zero valent iron nanoparticles were prepared and applied for the removal of natural organic matters (NOMs) from aqueous solutions under different experimental conditions. METHODS The nanoadsorbents prepared by wet impregnation method, then characterized using Scanning Electron Microscopy, Energy Dispersive Spectroscopy, X-Ray Fluorescence an...

A novel nanoadsorbent for the removal of heavy metal ions is reported. Cotton was first hydrolyzed to obtain cellulose nanocrystals (CNCs). CNCs were then chemically modified with succinic anhydride to obtain SCNCs. The sodic nanoadsorbent (NaSCNCs) was further prepared by treatment of SCNCs with saturated NaHCO3 aqueous solution. Batch experiments were carried out with SCNCs and NaSCNCs for th...

In this workN2,N6-di(thiazol-2-yl)pyridine-2,6-dicarboxamide (DPD), was synthesized via reaction of 2-aminothiazole and 2,6- pyridinedicarboxylic acid in n-methylpyrrolidine. The obtained (DPD) was characterized with nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared (FT-IR) spectroscopy, and elemental analysis. Finally, a novel magnetic nanoadsorbent was synthesized by m...

BACKGROUND Chromium (VI) has toxic and carcinogenic effects. So, determination and speciation of chromium in environmental samples is very important in view of health hazards. In this study, solid phase extraction (SPE) based on bulky amine-functionalized bimodal mesoporous silica nanoparticles (NH2-UVM-7) as a novel nanoadsorbent was applied for preconcentration and speciation of chromium (III...

toluene and benzene were eliminated using multi-walled carbon nanotubes (mwcnts). in order to investigate influence of acid treatment on the mwcnts adsorption capacities, the mwcnts were functionalized by nitric acid (10 m) under reflux conditions for 2 h. fourier transform infrared (ftir) and raman spectroscopy were employed to confirm the formation of functional groups on the nanotubes surfac...

For the adsorption of copper (II) and zinc ions from polluted water, an efficient inexpensive nanoadsorbent; nickel ferrite-modified montmorillonite nanocomposite was synthesized by co-precipitation mechano-chemically modified with salts iron. The natural MMT, (NiFe2O4-Mod MMT) nanoadsorbent were characterized several techniques including Fourier transform infrared spectroscopy, X-ray diffracti...

Nanoparticles of titanium diboride (TiB2) coated with a conductive polymer and subjected to an oxidizing agent was carried out in this research. TiB2 nanoparticles polypyrrole (PPy) were studied using XRD TEM techniques. Nitrogen adsorption desorption properties are covered modified understand better the surface zone, structural features, pore geometries nanoparticles. The water-based hazardous...
