- •
TFC RO membranes are prepared using a bis-founctional monomer and a tetraacyl biphenyl chloride as a cross-linking reagent.
- •
The performance of polyamide film can be adjusted by control of the fraction of the two monomers.
- •
The water flux of 43.7 L/m2h and the salt rejection of 99.7% are achieved for PAI-70.
