Abstract

PES hollow fiber composite nanofiltration membranes were prepared by interfacial polymerization;the effects of preparation conditions on PES composite NF were discussed.The experimental results show that polymerization reaction time,trimesol chloride concentration,piperazine concentration,acid absorbent-triethylamine concentration have remarkable effect on composite nanofiltration membrane performance.At the same time,the secondary reaction could improve NF rejection and the rejection of 2 g/L Na_2SO_4 could reach 99.2%.
