Abstract：

Polyethersulfone (PESU) hollow fiber substrate membranes were prepared via non-solvent induced phase separation (NIPS). Piperazine (PIP) and diethanolamine (DEA), which exhibits good hydrophilicity, were selected as aqueous phase monomers to form a polyamide separation layer on the inner surface of the PESU substrate membrane through interfacial polymerization (IP) with trimesoyl chloride (TMC). The hollow fiber nanofiltration membranes were characterized using ATR-FTIR, XPS, SEM, Zeta potential analyzer and water contact angle meter. The effect of DEA content in the aqueous phase on the separation performance of the nanofiltration membranes was investigated. The results showed that DEA was successfully introduced into the polyamide separation layer. With the increase of DEA proportion, the surface morphology of the polyamide separation layer changed significantly; the thickness of the separation layer decreased, the negative charge on the membrane surface was reduced; while the hydrophilicity and water flux improved. The optimal aqueous phase composition was determined as follows: DEA mass fraction of 1.2% and PIP mass fraction of 0.8%. Under this condition, the pure water flux was 67.0 L/(m2·h), which was 1.74 times that of the membrane without DEA addition. The molecular weight cut-off (MWCO) was 1 605 Da, and the rejection rates for Na2SO4, MgSO4, MgCl2 and NaCl were 91.2%, 86.4%, 38.1% and 25.4%, respectively. A 160-hour continuous filtration test showed that the membrane performance was stable.
