Nanozeolite-Impregnated Polysulfone/Polyethylene Glycol Nanocomposite Membrane for Ion Adsorption Application

Abstract

Polysulfone (PSf) is a high-performance polymer often used in water treatment applications. Polyethylene glycol (PEG) and Nanozeolite (NZ) were used as additives to improve the membrane’s porosity, chemistry, and overall performance in ion adsorption. PSf, PSf with PEG, and PSf with PEG and varying concentrations of Nanozeolite were prepared via non-solvent induced phase separation (NIPS) and tested using: Scanning Electron Microscopy (SEM) for the surface morphology, Fourier Transform Infrared Spectroscopy (FTIR) for the chemical composition, Contact Angle Goniometer for the wettability, Zeta Potential for the stability, and conductivity test through salt-water bath for ion adsorption application.
