Arsenic (As) in groundwater and surface water is a worldwide problem possessing a serious threat to public health. In this study, a magnetic ferrite, was synthesized and investigated for its As(V) removal efficiency. The adsorption of As(V) by magnetic ferrite exhibited an L-shaped nonlinear isotherm, suggesting limiting binding sites on the adsorbent surface. The As K-edge X-Ray Absorption Nea...

Among the modern oncological therapies, one of most promising is based on tumor hyperthermia with magnetic nanoparticles resulting from crystallization iron and cobalt oxides. We synthesized core–shell perchlorate-CoxFe3−xO4 (x = 0; 0.5; 1.0) via co-precipitation method stabilized them in aqueous suspensions. Fine granulation dispersed ferrophase was revealed by Transmission Electron Microscopy...

Ultrahigh efficient and effective electromagnetic-interference (EMI) shielding composites have been fabricated with the combination of Polyaniline zinc-cobalt ferrites (Co1-xZnxFe2O4, 0.1 ? x 0.4). Ferrite nanoparticles synthesized via sol-gel method were functionalized to polyaniline in situ polymerization. Average crystallite sizes estimated using Debye–Scherrer Rietveld found be between 20-3...

The E. coli inactivation using hydrogen peroxide (H2O2) and cobalt ferrite granulated catalyst was investigated in a fixed-bed flow reactor. CoFe2O4 synthesized by the co-precipitation method, granulated, annealed at 1150°C. X-ray diffraction analysis used to identify crystal structure of catalyst. demonstrates good catalytic activity for bacteria presence H2O2. An increase concentration increa...

magnetic nanoparticles of cobalt-zinc ferrite (co0.5zn0.5fe2o4) have been synthesized in a homogeneous aqueous solution at room temperature by co-precipitation method without any template and subsequent heat treatment. synthesis of material is confirmed using xrd from the report of single phase polycrystalline ferrite material and also determined lattice constant. atomic absorption spectrophoto...

nano-structured lanthanum strontium cobalt ferrite, la0.6sr0.4co0.2fe0.8o3 (lscf), was successfully synthesized via co-precipitation method using metal nitrates as starting materials. effects of precipitating agent and calcination temperature on the phase composition and morphology of synthesized powders were systematically studied using x-ray diffraction (xrd) and field emission scanning elect...
