摘      要：Improving the permeate flux but retaining the rejection of thin-film composite(TFC)polyamide nanofiltration(NF)membrane is a high requirement for *** this work,a calcium ion(Ca^(2+))coordinated polyamide(PA)NF membrane was prepared by directly adding CaCl_(2) to the piperazine(PIP)aqueous solution during the interfacial polymerization *** to the coordination interaction between Ca^(2+)and the amide bond in PA active layer.
