Abstract :
A new polyethersulfone (PES) microfiltration (MF) membrane was
fabricated via phase inversion method using a melamine-modified
zirconium-based metal-organic framework (MOF). The wettability and
permeability of the membrane were measured using water contact
angle and pure water flux (PWF), respectively. By introducing the
MOF additive (0.1 wt. %) to the membrane matrix, the performance
of the membrane in the separation of the oil-water mixture (different
oil concentrations of 300 and 500 mg/L) was enhanced. The flux
recovery ratio (FRR) of the modified membrane was significantly
increased to 90.76 % compared to that in the bare membrane (20.41
%). Furthermore, the antifouling property was considerably improved.
