arsenic magnetic separation

Research on magnetic seeding flocculation for arsenic ...

2010-6-18  The magnetic flocs with arsenic can be rapidly and efficiently removed by magnetic separation, even if the floc is very fine. This is because the strong magnetic force ( F m ) acts on magnetic particles when they move through a magnetic field ( H ) [6] : (1) F m = V M ( H ) d H d x where V is the volume of the magnetic particle, and M ( H ) is ...

2011-4-15  4. Conclusions. The products of conventional and surfactant-assisted ball-milling of magnetite powder were tested as potential arsenic adsorbents able to be recovered by means of a low-field magnetic separation process. Large hematite-coated Fe 3 O 4 particles obtained without the addition of surfactant were found to be much more efficient to ...

2020-4-21  Spinel ferrite particles (Fe3O4, MnFe2O4, and CoFe2O4) were investigated as magnetic nanosorbents for removing arsenic from spiked water samples. The nanosorbents were collected via magnetic separation from aqueous solutions spiked with an arsenic concentration that mimics the amount of this contaminant in real water samples. This research shows that using amounts of CoFe2O4 or

Ferrous Magnetic Nanoparticles for Arsenic Removal from ...

Arsenic in water is currently a global concern due to the long-term exposure that could affect human health. In this study, magnetic nanoparticles (MNPs), CoFe2O4, and MnFe2O4 were successfully synthesized and applied to remove arsenic (As) from water. The MNPs were characterized using different techniques, such as scanning electron microscope (SEM), Brunauer–Emmet–Teller (BET), and ...

2015-3-21  Arsenic is a ubiquitous element in the environment. Because of its prevalence in nature and its toxicity, the potential for arsenic contamination of water, air, and soil from both geological and anthropogenic sources is a significant environmental health concern (Smedley and Kinniburg 2002; Ng et al 2003).Elevated concentrations in surface water and groundwater of up to 100–5000 μg L −1 ...
