摘要

Abstract

A new aromatic diamine

5-diaminobenzoylpiperazine (3

5-DABP)

was synthesized from 3

5-diaminobenzoic acid and 1-formyl piperazine.The structure of 3

5-DABP was identified by FT-IR spectra and 1H NMR spectra.With 3

5-DABP as aqueous monomer and trimesoyl chloride (TMC) as organic monomer

thin film composite (TFC) nanofiltration membranes were prepared by interfacial polymerization technology.The salt rejection order of these TFC membranes is Na

MgSO

MgCl

NaCl.This sequence indicates that the membranes are negatively charged.
