Abstract

Abstract Heavy metal toxicity is highly demanding and challenging to clean up the pollutants. To recover the issues mentioned above, we propose a hydrothermal synthesis of zeolite (NaX-UP). Further surface modification by poly-ethylenimine (PEI) could turn to be amine-modified zeolite nanosheets (zeolite NSs) possessed plenty of hydroxyl and amino groups (Al-O, Si-O-Si, Si-OH and NH2) on their surface, decorated with magnetic nanoparticles (Fe3O4 NPs), that are enabled to bridge with inter and intramolecular hydrogen bonding an additionally electrostatic interaction might be a significant role. Further, this can be converted into magnetic bead crosslinking with sodium alginate immersed in an excess calcium chloride solution. The-as formed Fe3O4 NPs decorated amine modified zeolite alginate bead denoted to be (Fe3O4 NPs decorated @PEI-zeolite NSs alginate bead) upholding a significant advantage would aim to clean up the anionic pollutants are [As(V) & V(V)] from an aqueous solution.
