 The study presents the preparation and characterization of abstract nanocomposite membranes, NCMs, made of poly, vinylidine fluoride hexafluoropropylene, PVDFHFP, with different yttrium carbonate and magnetite loadings. The NCMs exhibit dual adsorption capacity over neutral arsenite and anionic arsenate species, with the maximum adsorption capacities of 92.82 and 137.08 mg g-1 for as, 3, and as, EV, respectively. The membranes are easily activated and reused without significant efficiency loss, making them low-cost, reusable, and efficient water remediation systems suitable for the long-term removal of arsenic species under real polluted surface and groundwater conditions.
