Removal of Ni(II) by magnetic nanoparticles

Copper adsorption onto synthesized nitrilotriacetic acid functionalized Fe3O4 nanoparticles: kinetic, equilibrium and thermodynamic studies

“…Although 16 copper is essential micronutrient for animals and takes part as a 17 cofactor in many metalloproteins and as an activator of some 18 enzyme systems [6]. However, ingestion of excess concentration of 19 Cu(II) causes hepatic and renal damage genetic disorder and it may 20 also causes nausea, vomiting, diarrhoea etc. [7].…”

“…34 During the recent year adsorption on magnetic nanoparticles 35 have gain much popularities due to its high surface area to volume 36 ratio, biocompatibility, high physiochemical stability, ease in 37 operation, and recycling in external magnetic field [15][16][17][18]. Many 38 magnetic nanoparticles such as magnetite (Fe 3 O 4 ) [19], hematite 39 (ɑ-Fe 2 O 3 ) [20], and goethite (ɑ-FeOOH) [14] have been used for the 40 removal of pollutant from aqueous media. However, bare magnetic 41 nanoparticles easily get oxidize in air.…”

Synthesis of bimetallic Fe–Zn nanoparticles and its application towards adsorptive removal of carcinogenic dye malachite green and Congo red in water

“…The error functions, Chi square test (χ 2 ), sum of the square of the error (SSE), and residual root mean square error (RMSE) were calculated across the studied range using the solver add-in with Microsoft's Excel spreadsheet by the following Eqs. (5)-(7) [31]:…”

“…The High Gradient Magnetic Separation (HGMS) of coated magnetic nanoparticles' core with bio-functionalized surface has been used in many magnetic separations, especially in biological and biomedical applications [32][33][34][35]. The iron oxide nanoparticles have high saturation magnetization values, low toxicity, low price, and the surface chemical modi cation ability which makes them suitable absorbents for heavy metal separation during the water puri cation process [36,37].…”
