Abstract :In the production of polymeric membranes used in water treatment by the non-solvent-induced phase separation insert ignore into journalissuearticles values(NIPS); method, the materials used in the membrane casting solution and the interaction of these materials greatly affect the properties and performance of the obtained membranes. In this study, polyethersulfone insert ignore into journalissuearticles values(PES); membranes are produced by the NIPS method using two different solvents, dimethyl sulfoxide insert ignore into journalissuearticles values(DMSO); and N-methyl-2-pyrrolidone insert ignore into journalissuearticles values(NMP);, and polyvinylpyrrolidone insert ignore into journalissuearticles values(PVP); as pore-forming agent. Chemical functional groups and morphologies of the produced membranes are investigated by Fourier transform infrared insert ignore into journalissuearticles values(FTIR); spectroscopy and scanning electron microscopy insert ignore into journalissuearticles values(SEM);, respectively. The viscosity of the membrane casting solutions and the hydrophilicity, porosity, mean pore size, and mechanical properties of the membranes are characterized. The pure water flux insert ignore into journalissuearticles values(PWF); of the membranes is determined at 1 and 3 bar pressures. The Hansen solubility parameters insert ignore into journalissuearticles values(HSP); of the materials used in membrane production are calculated and the effect of the interactions of DMSO, NMP, and PVP with PES and/or non-solvent insert ignore into journalissuearticles values(water); on the membrane properties are investigated.
