Fabrication and evaluation of multiple template cross-linked molecularly imprinted electro spun nanofibers for selective extraction of nickel and vanadyl tetraphenylporphyrin from organic media

Abstract: A nickel vanadyl molecularly imprinted nanofiber (NVMIN) was developed by the electrospinning technique, employing polyethylene terephthalate (PET) and linear polyethylenimine (L-PEI) as the matrix polymers, nickel tetraphenylporphyrin (NTPP) and vanadyl tetraphenylporphyrin (VTPP) as the mixed-template molecules. The fabricated NVMIN was evaluated as a sorbent for the removal of NTPP and VTPP from organic media. The effects of trifluoroacetic acid (TFA), dichloromethane (DCM), dimethyl sulphoxide (DMSO), pent… Show more

“…Scanning Electron Microscopy (SEM) characterization instrumentation is essential to determine the surface morphology structure of the polymer material samples [82]. Electrospinning fibres synthesized using TFA polymers for solution concentrations of less than 18 % emitted from low-viscosity solutions split into droplets due to the lower polymer amount and density required to form a stable beam [67]. Meanwhile, beads were observed in solution concentrations between 20 % and 24 % w/v.…”
