Fabrication, characterization and application of electrospun polysulfone membrane for phosphate ion removal in real samples.

Due to simplicity and flexibility, electrospinning technique can produce many types of fibers at nanoscale via different operational parameters for various applications including industrial wastewater treatment, air filtration and so on. Nonetheless, the study on the electrospinning operational parameter is very limited and many researchers are still using trial-and-error method to design their targeted fiber. In this study, a series of electrospun polysulfone (PSF; 20% w/v) nanofibrous membranes that made up from different ratios of dimethylformamide (DMF) and tetrahydrofuran (THF) mixtures in order to achieve different dielectric constant (ϵ) of solvent system.
