A thin-film nanocomposite (TFN) membrane containing porous MCM-41 silica nanoparticles (NPs) was prepared by the in situ interfacial polymerization (IP) process. Aqueous m-phenyl diamine (MPD) and organic trimesoyl chloride (TMC)-NPs mixture solutions were used in the IP process. Porous MCM-41 (∼100...
