Study the adsorption properties of magnetite nanoparticles in the presence of different synthesized surfactants for heavy metal ions removal

Nanofibrous ε-polycaprolactone scaffolds containing Ag-doped magnetite nanoparticles: Physicochemical characterization and biological testing for wound dressing applications in vitro and in vivo

“…Magnetite is also a very common mineral. It is found in a number of igneous rocks and is also a major mineral component of many types of ore deposits [ 27 ]. Magnetite crystallizes in the inverse cubic spinel structure and contains both Fe 2+ and Fe 3+ ions, with the former occupying strictly the octahedral (B) sites and the latter occupying both the tetrahedral (A) and the octahedral (B) sites [ 28 ], resulting in the chemical formula of Fe 3+ [Fe 3+ Fe 2+ ]O 4 2− .…”

Green Synthesis, Characterization and Application of Natural Product Coated Magnetite Nanoparticles for Wastewater Treatment

“…There are reports in the existing literature that MNPs have the potential to adsorb heavy as well as toxic metal ions such as Hg 2+ ,Cd 2+ ,Pb 2+ ,Co 2+ ,Cu 2+ , etc. [43,[58][59][60]. We have investigated the ability to remove toxic metal ions Co 2+ and Cu 2+ from aqueous medium via adsorption onto the synthesized JC-Fe 3 O 4 and CT-Fe 3 O 4 NPs.…”

Synthesis of FeO@SiO2–DNA core–shell engineered nanostructures for rapid adsorption of heavy metals in aqueous solutions

“…1 Globally, heavy metal ions are mainly introduced into different ecosystems through anthropogenic activities. 2 Such activities can include mining, smelting, 3 chemicals and petrochemical manufacturing, 4 energy generation, 1 domestic and industrial waste discharges, 5 agricultural wastes, 6 metallurgy, 7 and construction. 8 The most toxic and hazardous heavy metal ions in water include As(III), As(V), Cr(III), Cr(VI), Cu(II), Hg(II), Pb(II), Cd(II), Ni(II), Zn(II), 9 and Mn(II).…”

“…1 This exposure increases the chance of suffering cancer, nausea, mental disorders, liver and kidney failures, 2 bone deformation, 11 lethargy, hypertension, and depression. 3 Considering the high stability of heavy metal ions in water sources, the allowable limits established by the World Health Organization (WHO) can be easily exceeded. 12 Some heavy metal ions can easily migrate, reaching groundwater sources and affecting the quality of drinking water.…”
