Novel nanofiltration membrane with low concentration of polyvinylchloride: Investigation of solvents’ mixing ratio effect (Dimethyl acetamide/Tetrahydrofuran)

In the current research polyvinylchloride (PVC) nanofiltration membrane was prepared using Dimethyl acetamide (DMAC)/Tetrahydrofuran (THF) as solvents via the phase inversion method. The effect of solvents’ mixing ratio (DMAC to THF) in the casting solution and also phase separation time in coagulat...

Summary:In the current research polyvinylchloride (PVC) nanofiltration membrane was prepared using Dimethyl acetamide (DMAC)/Tetrahydrofuran (THF) as solvents via the phase inversion method. The effect of solvents’ mixing ratio (DMAC to THF) in the casting solution and also phase separation time in coagulation bath on membrane flux and selectivity were studied. The membrane tensile strength measurement and scanning electron microscope (SEM) analysis were also carried out in membrane characterization. The highest membrane selectivity and flux were found at (85:15) solvents’ mixing ratio (DMAC to THF).
