Newly modified silica-based magnetically driven nanoadsorbent: A sustainable and versatile platform for efficient and selective recovery of cadmium from water and fly-ash ameliorated soil

Enhanced Exfoliation Effect of Solid Auxiliary Agent On the Synthesis of Biofunctionalized MoS2Using Grindstone Chemistry

“…The corresponding kinetic parameters and the correlation coefficients calculated from the experimental data are listed in Table S2 (Supporting Information). The experimental data could be well fitted to the pseudo‐second‐order kinetic model (Figure c), indicating that the adsorption capacity is proportional to the number of functional sites occupied on the MoS 2 nanosheets, and the adsorption of Pb II on MoS 2 ‐CS nanosheets is thus controlled by chemisorption involving surface complexation with the amino and hydroxyl groups on the surface of the MoS 2 nanosheets . The results in Figure S1 (Supporting Information) show that the contact time for the equilibrium state may be influenced by the initial concentration of Pb II .…”

Acetoacetanilide-functionalized Fe3O4 nanoparticles for selective and cyclic removal of Pb2+ ions from different charged wastewaters

“…Unlike the Freundlich isotherm, the Langmuir isotherm is based on the monolayer and homogenized coverage of the adsorbent surface, where all sorption sites are identical and energetically equivalent. The experimental equilibrium data at different temperatures were evaluated according to the linear equations of these models given below, 15 and the curve tting results are compiled in Table 2…”

“…[12][13][14] Furthermore, these magnetically responsive nanoparticles allow simple and facile recovery and recycling of the metals, which is deemed an essential feature to close the resource/waste loop. 15 Therefore, fabrication of these nanomaterials is currently undergoing exciting developments with increasing achievements for Pb 2+ adsorption. The research group of Zhang reported silicabased core-shell nanomaterial prepared via a controllable sol-gel process as an efficient adsorbent for Pb 2+ removal.…”

Hybrid silica aerogel nanocomposite adsorbents designed for Cd(II) removal from aqueous solution

“…For example, 100 mg poly(1‐vinylimidazole)‐grafted Fe 3 O 4 @SiO 2 could adsorb 0.00005 g/L of Cd(II) cations in 10 min at pH range of 5–10 illustrating 42.1 mg/g adsorption capacity (Shan et al, ). In another work, 1,000 mg of NH 2 @SiO 2 @MNPs (MNPs = magnetic nanoparticles) adsorbed 0.050 g/L of Cd(II) ions in 30 min (at pH = 6) and the adsorption capacity was reported to be 200 mg/g (Sharma, Puri, Monga, & Adholeya, ). In another research, 3.2 mg of polyacrylic acid‐coated Fe 3 O 4 was applied in removal of 0.005 g/L Cd(II) ions in 10 min (at pH = 6) and the sorption capacity was 2.683 mg/g (Alimohammadi, Shadizadeh, & Kazeminezhad, ).…”
