Arsenite removal from aqueous solutions by γ-Fe2O3–TiO2 magnetic nanoparticles through simultaneous photocatalytic oxidation and adsorption

Arsenic removal by nanoparticles: a review

“…The As(V) capacities were determined to be 4600 mg kg −1 (Fe 2 O 3 ), 6711 mg kg −1 (Fe 3 O 4 ), 4904 mg kg −1 (Fe 2 O 3 ), and 4780 mg kg −1 (Fe 3 O 4 ) at contact times of 1 and 24 h respectively. Yu et al (2013a) applied a universal, simple method in the preparation of the cellulose-based magnetic iron oxide nanoparticles through a green pathway. The Fe 2 O 3 nanoparticles were uniformly dispersed in the cellulose matrix due to the strong interaction between cellulose and Fe 2 O 3 nanoparticles.…”

Dispersion–precipitation synthesis of nanosized magnetic iron oxide for efficient removal of arsenite in water

“…Epidemiological studies revealed that long-term exposure to arsenic-contaminated drinking water could lead to serious health problems such as hyperkeratosis, peripheral vascular diseases, diabetes, anemia, cancers, as well as disorders of the immune, nervous, and reproductive systems [1][2][3][4][5][6][7][8][9][10]. The inorganic species, including As(III) (arsenite) and As(V) (arsenate), are the main forms of arsenic in natural water.…”

Synthesis of magnetically recoverable ferrite (MFe2O4, M Co, Ni and Fe)-supported TiO2 photocatalysts for decolorization of methylene blue

“…Recently, magnetic composite particles that contain TiO 2 were developed as heterogeneous photocatalysts [11,12]. These magnetic photocatalysts can be recovered by applying an external magnetic field and reused [13][14][15]. Spinel ferrite is a good candidate material for use in supports for the photocatalytic degradation of dyes or organic compounds [16,17].…”
