Recycling Polysulfone by Electrospinning and Testing Its Nanofibers in Water Desalination

Abstract

A polysulfone filter used in a kidney dialysis machine was used. The polysulfone fibers were mechanically, chemically, and thermally treated. Then mixed with an appropriate concentration of PVP. The as mixed dissolved in DMF, taking into account the appropriate viscosity. The solution was electrospinning. The distance between the collector and the spinning needle tip was kept to 15cm, and the applied voltage was 24Kv. The structural and optical properties of the spun mat were studied, and the nanostructure of the mat was confirmed. The mat's effectiveness in absorbing NaCl ions was tested, and it was found that a 0.057mm thick mat removed 22% of the salinity, confirming its potential as a seawater desalination filter when used with other polymers such as polyamides.
