The composite nanofiltration membranes were prepared via interfacial polymerization of tetraethylenepentamine (TEPA) and 1,3,5-benzenetricarbonyl trichloride (TMC). The improved performance of the composite nanofiltratiom membranes by adding calcium chloride in aqueous phase during the interfacial polymerization was verified in terms of pure water permeability, rejection of different solutes including...
