Preparation of amidoxime-modified polyacrylonitrile (PAN-oxime) nanofibers and their applications to metal ions adsorption

Laccase Immobilization by Chelated Metal Ion Coordination Chemistry

“…Polyacrylonitrile (PAN) nanofibers after surface modification have been studied and proved to be ideal support for laccase immobilization [17]. Amidoxime polyacrylonitrile (AOPAN) prepared by the chemical modification of the nitrile group was known as good adsorbent for metal ions [18]. Feng [19] has proved that after immobilized onto the surface of Fe(III) chelated AOPAN nanofibrous membrane, catalase showed better stabilities.…”

Synthesis of amidoximated polyacrylonitrile fibers and its application for sorption of aqueous uranyl ions under continuous flow

“…To improve the sorption capacity of sorbents, many attempts have been made for chemical modification of sorbent surfaces using functional groups such as amidoxime [3,14,15], imidazole [16], and metal oxides [4,17,18], which possess chelating abilities toward U(VI) ions. As commonly used sorbents are in powder form, their utilization as a filter material is not convenient due to the difficulty in the isolation of the solid from the solution medium following the sorption stage.…”

Adsorption of Multiwalled Carbon Nanotubes on Electrospun Polycaprolacton Nanofibers

“…[28][29][30][31] The nanofibers have interesting characteristics such as large surface area per unit mass, high porosity, high gas permeability, high fiber aspect ratio, and small interfibrous pore size. Due to these unique characteristic, the nanofibers shows a wide range of applications such as sensor, 32 scaffolds in tissue engineering, 33 drug delivery, 34 wound dressing, 35 nanofibers as a filter, 36 protecting clothing, 37 nanofiller materials.…”
