Evaluation of the antifouling and photocatalytic properties of novel poly(vinylidene fluoride) membranes with a reduced graphene oxide–Bi2WO6 active layer
Liang Zhu, Yukun Li
Immobilization of reduced graphene oxide (RGO)–Bi2WO6 is an ideal method for obtaining antifouling membranes for membrane distillation (MD) processes. Poly(vinylidene fluoride) membranes modified with RGO–Bi2WO6 were successfully obtained with a double-layer coating method through non-solvent-induced phase separation. The water contact angle was improved by about 30° by RGO–Bi2WO6; this indicated that the surface modification obviously increased the membrane hydrophobicity. The high desalination rate proved that all of the prepared membranes were appropriate for the MD process. The RGO–Bi2WO6-modified membranes achieve 26.26–59.95% removal rates in 10 mg/L aqueous ciprofloxacin under visible light for 7.5 h. It was possible to erase strongly bound foulants and recover the prepared membrane's permeation flux by 3 h of visible-light irradiation. The RGO–Bi2WO6-modified membrane with a high hydrophobicity, fouling mitigation, and photocatalytic capability presents huge potential for the treatment of high-salt antibiotic wastewater use in the MD process. © 2017 Wiley Periodicals, Inc.
