Effect of Fe3O4 nanoparticles on magnetic xerogel composites for enhanced removal of fluoride and arsenic from aqueous solution

Optimization Study for Desorption of Arsenic and Regeneration Performance on Magnetic Carbon Xerogels for Environmental Sustainability

“…The molar ratios were M/R = 0.07, R/C = 100, R/W = 0.04, and R/F = 0.5. For full details on the synthesis procedure of magnetic xerogels, please refer to [11].…”

Optimizing the performance of As(III) and As(V) adsorption process on magnetic carbon xerogel nanocomposites from aqueous solution and natural groundwater wells

“…The magnetic nanoparticle applications were signi cantly increased for the removal of contaminants due to high surface area, small particle size and performance behavior of magnetic materials, the chemical and physical properties, and easy separation through an external magnetic eld (Tang and Lo 2013;Mehta et al 2015). The present work proposes the synthesis of magnetite nanoparticles (MNPs) prepared by conventional co-precipitation using the Fe 3+ /Fe 2+ molar ratio established by the reaction stoichiometry regarding the results obtained from (Khamkure et al 2022). This synthesis method is that considered simple, cheap, high yield and potential to prepare in high production of nanoparticles, control in nanoparticle's distribution, low temperature requirement, but the limitation of this technique is non-environmentally friendly chemical due to utilizing strong base chemicals (Nisticò 2021).…”

“…The adsorption enthalpy and the effect of temperature were determined using the optimal values resulting from the implemented experimental design and application of groundwater. Most of the investigations of xerogel carbons for water treatment were applied for aqueous solution however few relevant studies used groundwater for the removal of arsenic contamination by using magnetite and magnetite nanoparticle composite of xerogels (Khamkure et al 2021(Khamkure et al , 2022. To our knowledge, this is the rst study to apply magnetite nanoparticles incorporating xerogel carbons with direct sonication for As(III) and As(V) removal from natural groundwater.…”

Enhanced remediation of As(iii) and As(v) by new zirconium-loaded attapulgite and its mechanisms in the aquatic environment

“…8,9 In particular, adsorption is considered as an ideal method as it can directly remove As from water at a lower cost and is more applicable and feasible than other treatments. 10,11 To date, numerous adsorbents, such as iron oxides/hydroxides, 12,13 calcium oxides/hydroxides, 14 aluminum oxides/hydroxides, 15 biochar, 16 activated char, 17 and modified clay minerals, 18 have been produced for As remediation in waters. However, iron oxides/hydroxides aggregate easily and are instable.…”
