Abstract :
A new polyethersulfone (PES) ultrafiltration (UF) membrane, was prepared using metal-organic framework (MOF), UiO-66-NH2. The membrane performance was investigated by pure water flux (PWF), flux recovery ratio (FRR), and long-term performance capability and the results were very positive. Notable decrease in water contact angle (WCA) and notable increase in porosity were found for the modified membranes. By addition of MOF into the polymer matrix, the FRR value was increased (59.2 to 95.22%) for optimal modified membrane. The membrane was tested by oily wastewater filtration, and the results showed improvement in high rejection during the long-term filtration (99% rejection).
