【Abstract】 The rules to form NF-TFC membranes were studied according to principles of interfacial polymerization. The interaction between the performance of NF-TFC membranes and some interfacial polymerization factors were investigated. The experiment results showed that the draining time, the polymerization time and the post-treatment temperature exerted influence on the flux and salt rejection of membranes by affecting the interfacial polymerization while the immersion time did not have a clear influence on them. These results proved that there were some interrelation between the rules of interfacial polymerization and the performance of membranes.更多还原
