Synthetic zeolite derived from coal fly ash decorated with magnetic alginate bead: Application to detoxification of arsenic and vanadium

Abstract Heavy metal toxicity is highly demanding and challenging to clean up the pollutants. To recover issues mentioned above, we propose a hydrothermal synthesis of zeolite (NaX-UP). Further surface modification by poly-ethylenimine (PEI) could turn be amine-modified nanosheets (zeolite NSs) possessed plenty hydroxyl amino groups (Al-O, Si-O-Si, Si-OH NH 2 ) on their surface, decorated with magnetic nanoparticles (Fe 3 O 4 NPs), that are enabled bridge inter intramolecular hydrogen bonding an additionally electrostatic interaction might significant role. Further, this can converted into bead crosslinking sodium alginate immersed in excess calcium chloride solution. The-as formed Fe NPs amine modified denoted @PEI-zeolite NSs bead) upholding advantage would aim anionic pollutants [As(V) & V(V)] from aqueous
