Development of Adsorptive Materials for Selective Removal of Toxic Metals in Wastewater: A Review

“…The rhombohedral, hexagonal, weakly ferromagnetic hematite nanoparticles are considered the highly stable form of iron oxide, which also exhibits anti-corrosive properties and has been used in energy and catalytic functionalities [80][81][82]. These nanoparticles have been applied in wastewater treatment for metal removal [83].…”

Morphologies and magnetic properties of α-Fe2O3 nanoparticles calcined at different temperatures

“…24,25 The reaction of different molar ratios of FeCl 3 with NaOH was able to prepare needle-like a-Fe 2 O 3 with different particle sizes. 26 By adding surfactants, stabilizers, inorganic anions, or changing the concentration and pH of the reaction solution, researchers have prepared a-Fe 2 O 3 with different structures, such as nanorods, 27 nanowires, 28 nanoribbons, 29,30 nanotubes, 31 microcubes, 32 spheres, 33,34 microcycles, 35 nanoflowers, 36 and dendrites. 37 In this paper, a-Fe 2 O 3 particles with different morphologies were prepared by the coprecipitation method.…”

Synthesis of composites from hydroxypropyl cellulose:iron (III) oxide nanoparticles

“…Hematite (α-Fe 2 O 3 ) nanoparticles have attracted a lot of attention because of low cost, low toxicity, excellent chemical stability, and tunable optical and magnetic properties. 17 Because HPC is a polymer formed on the bases of the polysaccharide's main chain, researchers can learn more about the interaction of organic and inorganic elements by studying transitional temperatures under the influence of nanoparticles. [18][19][20] Furthermore, the thermal efficiency of the final composite materials is essential to ensure that the nanocomposite product is compatible with a variety of applications.…”
