Ion exchanger using electrospun polystyrene nanofibers

Nanofibrous filtering media: Filtration problems and solutions from tiny materials

“…More recently, the fibrous materials are recognized as a support for ion-exchange functionality due to ease of preparation, contact efficiency, physical requirements of strength and dimensional stability [37]. Polymeric nanofiber based ion exchanger has high swelling behavior compared to other media because of high surface area, porosity and capillary motion [24]. In addition, Polymer nanofiber ion exchanger is found to possess extremely rapid kinetics and higher ion-exchange capacity [24].…”

Electrospun nanostructured polystyrene as a new coating material for solid-phase microextraction: Application to separation of multipesticides from honey samples

“…Polystyrene (Scheme 1) is an inexpensive, available polymer which includes phenyl and alkyl groups, so is capable to absorb polar and apolar compounds. It has been applied for separation purposes in some reports [39,40] In the present work, polystyrene nanofibers were deposited on a stainless steel wire and used in the analysis of several pesticides with different polarities (diazinon, chlorpyrifosmethyl, malathion, propargite, bromopropyrate, tetradifon, permethrin) spiked to honey samples. The results showed the usability of polystyrene nanostructures in SPME as a highcapacity coating for the extraction of multipesticides from the highly complex matrix of honey.…”

Fabrication of electrospun polyacrylonitrile ion-exchange membranes for application in lysozyme adsorption

“…A conventional ion exchange resin usually has a gel or granular structure, composed of styrene or acrylic material [1]. However, micropore structures within the resin result in lower molecular adsorption/desorption rates, due to diffusion distance.…”
