| 英文摘要 | A green method to prepare asymmetric positively charged poly(arylene ether sulfone) nanofiltration (nf) membranes was explored by grafting water-soluble poly (ethylene imine) (pei) onto a poly (arylene ether sulfone) membrane containing tertiary amine groups (pes-ta) and cross-linking with poly(ethylene glycol) diglycidyl ether (pegdge). the modifications were shown to increase the positive charge and decrease the pore size of the pes-ta substrate. the optimized nf membrane displayed a pure water flux of 15.5 l m(-2) h(-1). membrane rejection nacl, mgcl2, and methyl violet (mv) (at a constant pressure of 4 bar) were measured to be 46.2%, 94.9%, and 99.8%, respectively. moreover, the membrane maintained excellent chlorine resistance during 100 h of exposure to chlorine. thus, the membrane shows potential for water desalination and purification applications.
