| Abstract: | Composite nanofiltration membranes were fabricated through interfacial polymerization.Membranes were prepared with diamine as aqueous monomer and trimesoyl chloride(TMC) as organic monomer on the support of polyethersulfone(PES) ultrafiltration membranes.Three different diamines were utilized as aqueous monomer respectively.They are o-phenylenediamine,m-phenylenediamine and p-phenylenediamine.The separation performance and the chlorine resistance of these membranes were compared.The salts rejection on four ... |
