Electrospun magnetic La2O3–CeO2–Fe3O4 composite nanofibers for removal of fluoride from aqueous solution

La2O3–CeO2–Fe3O4 composite nanofibers (LCF NFs) were fabricated via a facile electrospinning - calcination approach, and evaluated as an adsorbent for defluoridation from aqueous solution under batch mode. The pseudo-second-order (PSO) model described defluoridation characteristics well under 20 and...

Zusammenfassung:La2O3–CeO2–Fe3O4 composite nanofibers (LCF NFs) were fabricated via a facile electrospinning - calcination approach, and evaluated as an adsorbent for defluoridation from aqueous solution under batch mode. The pseudo-second-order (PSO) model described defluoridation characteristics well under 20 and 50 mg/L. F− adsorption under 288.15–308.15 K obeyed the Langmuir adsorption isotherm better with the maximum uptakes of 202.43–229.89 mg/g, respectively. The obtained thermodynamics constants involving Gibbs free energies change (ΔG
