Ferrous Magnetic Nanoparticles for Arsenic Removal from Groundwater

Arsenic in water is currently a global concern due to the long-term exposure that could affect human health. In this study, magnetic nanoparticles (MNPs), CoFe2O4, and MnFe2O4 were successfully synthesized applied remove arsenic (As) from water. The MNPs characterized using different techniques, such as scanning electron microscope (SEM), Brunauer–Emmet–Teller (BET), photoelectron spectroscopy (XPS). nanoscale size specific surface area achieved fast, selective, high As adsorption capacity. have mesoporous structure with mean pore diameter of 5 nm particle 30 nm. capacity these was determined through kinetic equilibrium experiments, multilayer obeyed Freundlich model equation observed, maximum capacities reached 250 mg/g for CoFe2O4 230 MnFe2O4. Furthermore, characteristics like regeneration reuse, several pH tolerances, non-ion interference, effective removal groundwater samples confirms nanomaterials’ potential future applications treatment systems combined separation.
