These thin-film composite membranes are based on highly crosslinked polyamides prepared from interfacial polymerization, and their further use is limited by their low water permeance. Recently, the polyamides can be doped with nanoparticles with well-structured pores (such as carbon nanotubes, graphene oxide, and zeolites) to increase water permeance. However, the thin-film nanocomposite (TFN) membranes show decreased ion rejection due to the defects between the polymers and nanoparticles. The objective of this work was to develop TFN membranes by incorporating metal-organic frameworks (MOFs) and metal- organic polyhedra (MOPs) in the selective polyamide layers. The effects of the processing conditions (for interfacial polymerization) and particle size on the desalination performance were thoroughly investigated. The addition of the MOFs increases water permeance by 175% for the RO applications while retaining the salt rejection. The addition of MOP in the NF membranes increases the water permeance by 66% while achieving excellent rejection for 2000 ppm Na2SO4.Keywords: Water purification; nanocomposites; reverse osmosis membranes; nanofiltration membranes; ZIF-8; Fe-MOP.","**To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
