چکیده مقاله:
A novel work was performed for fabrication and modification of composite nanofiltration (NF)membrane by polymerization reaction between polyethyleneimine (PEI) and triphthaloyldechloride(TPC). The main purpose of this work was water treatment. Polysulfone was the main polymer appliedas substrate. The result of reaction between PEI and TPC was the formation of polyamide layer on themembrane surface. SiO2 nanoparticles were used as modification agent. The fabricated membraneswere characterized by Scanning Electron Microscope (SEM), Atomic Force Microscope (AFM),contact angle measurement and FTIR analysis. Removal ofMgSO4 as one of the dissolved salts inwater was investigated and these fabricated membranes were utilized to remove MgSO4 from water.Properties of substrate in addition to properties of NF membrane such as steric-hindrance and Donnanexclusion led to a rejection of 89% for MgSO4
