Abstract：

The effects of piperazine concentration and aqueous contact time on the performance of composite nanofiltration membrane are studied. The mass fraction of piperazine is between 0.1% and 0.5%. The contact time of aqueous phase is between 60 s and 120 s. The obtained membranes were characterized with desalination test, infrared spectrum and zeta potential. The results show that, both the addition of concentration and aqueous contact time increase the amount of piperazine on base membrane, and ultimately improve the rejection of calcium chloride from 4% to 96%. The amount of polyamide layer formed from interfacial polymerization is a key structure factor to the increasement of the rejection of calcium chloride.
