摘　　要：With microporous polysulfone hollow fiber as the substrate, a polypiperazine amide nanofiltration composite membrane was prepared by interfacial polymerization in trimesoyl hexane solution as oil phase and piperazine aqueous solution as water phase. The conditions of the preparation, such as concentrations of monomer solutions, reaction time and temperature, annealing treatment, etc., were investigated. The hollow fiber composite herewith obtained showed high performance with water fluxes over 40 L·m -2·hr -1 and MgSO4 rejection of 93% under a pressure of 0.40 MPa.With microporous polysulfone hollow fiber as the substrate, a polypiperazine amide nanofiltration composite membrane was prepared by interfacial polymerization in trimesoyl hexane solution as oil phase and piperazine aqueous solution as water phase.
