Abstract
Polyvinylchloride (PVC) and graphene oxide (GO) embedded PVC ultrafiltration membranes were prepared via phase inversion method. GO has three significant groups such as hydroxyl, carboxyl and epoxy which can directly effect on membrane structure. The results of FTIR and XRD were revealed that GO prepared successfully. According to FESEM, adding the amount of GO in the mixed matrix of the membrane leads to dramatically change phase separation between solvent and non-solvent in water and ethanol bath coagulation thus the performance of membrane in pure water flux, contact angle, hydrophilicity and rejection of humic acid solution were significantly improved and sponge section of membrane was increase.
