Fabrication and Characterization of Nanozeolite-Modified High Impact Polystyrene (HIPS) Membranes for Nanofiltration

Abstract

The present study utilized high-impact polystyrene, a polymer with good mechanical, thermal and chemical stability, for its potential as a filter material and matrix for nanozeolite – a well-known adsorbent for wastewater treatment. Different concentrations of nanozeolite (0.25%, 0.5%, and 0.75%) were added to the high-impact polystyrene matrix and were fabricated intocomposite membranes via hand-casting method. The membranes were characterized using Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy, and Contact Angle Goniometer to discuss their functionality in the removal of nanocontaminants from wastewater like dyes. Results showed that nanozeolite can control the porosity and pore size of the High-impact polystyrene polymer while also improving its hydrophilicity; these are important considerations in the removal of organic dyes from wastewater.
