Abstract

The incorporation of imprinted polymers and electrospun nanofiber, which aims for continueable and better water treatment, has been quite challenging these days. But with simple incorporating method, it could be achieved. This study was conducted to incorporate these two technologies, with simple suspended method of Fe(III)-IIPs within PVA/GE pre-electrospinning solution. The process was carried out within 15kV, 0.25 mL/h, 60% RH, and 12 cm needle-collector distance in electrospinning apparatus settings. The FTIR characterization showed quite identical spectra, as an indication of stabilized polymeric network. SEM imaging vaguely showed linked fibers through spherical Gelatine encapsulation, with the majority of pore size distribution within nanoscale (below 100 nm). EDS analysis clearly detect the trace amount of iron element within the nanofiber mats, from the suspended particle of Fe(III)-IIPs, hence it can be state that the incorporation method has succeeded bringing Fe(III)-IIPs into nanofibers mats. Study also pointed constructive suggestion in accordance of poorly nanofiber substrate selection for better characterization data.
