Imprinted Polymer Nanoparticles Functionalized PAN Porous Electrospun Nano-membranes: An Effective Approach in Cr(VI) Adsorption

Porous electrospun nanofibrous ion imprinted membrane prepared for Cr(VI) ion elimination in wastewater.First, Cr(VI) ion imprinted polymer (IIP) were synthesized based on 1-vinylimidazole (1-VI) as a monomer.Porous electrospunnanofibrouspolyacrylonitryle (PNPAN) were prepared by electrospinning method. The IIPparticles loaded on PNPAN which functionalized by hydroxylamine hydrochloride and the obtained functionalized porous electrospun nanofibrous ion imprinted membrane (FPNFIIM) was recognition and fully characterized by various technic such as FT-IR, TGA, FESEM, EDS-FESEM and AAS techniques. The initial metal ion concentration, contact time, imprinting efficiency, FPNFIIM dosage and FPNF:IIP ratio optimization, release ability and reusability of FPNFIIM were compared with IIP, functionalized PAN porous electrospun nanofibrous (FPNF), PNPAN and non-imprinted polymer (NIP). Selectivity of FPNFIIM was checked in presence of Cr(III), Cu(II) and Cd(II) ions as analogous.
