Preparation and characterization of novel polysulfone membrane for wastewater treatment

Abstract

A novel polysulfone (PSU) mixed matrix ultrafiltration membrane containing functionalized carbon nanotubes with polyethylene glycol (PEG-CNTs) was prepared via the non-solvent induced phase inversion method (NIPS).
FTIR and TGA analyses confirmed the appropriate PEG-CNTs. pure water permeability and the bovine serum albumin (BSA) solution permeability are increased due to the increase in pore size after addition of PEG-CNTs
to the casting solution. Besides, this increment is may be attributed to the higher water uptake and hydrophilicity of the fabricated membranes. The morphology studies by SEM showed the wider surface pores of the PEG-CNTs incorporated membranes in comparison with those of the unfilled PSU membrane. Fouling resistance of the membranes assessed by BSA solution filtration revealed that 0.25 wt. % PEG-CNTs membrane had the best antifouling property. In addition, the results showed that the 0.25 wt. % PEG-CNTs membrane had the highest mean pore radius, porosity, and water flux.
