- •
Chitosan/PA6 NFP was prepared by electrospinning.
- •
The NFP exhibited greatly enhanced Cr(VI) adsorption via filtration.
- •
The NFP could be easily regenerated and reused.
- •
Amino groups were predominant chelation sites in adsorption.
- •
Cr(VI) was reduced to the less toxic form Cr(III) during the adsorption.
