Abstract:
Over the past decade, a remarkable attention in membranes study has been increased due to their wide applicability in coating, chemical purification, electrolytes, environmental protection, and substrates. Poly (vinylidene fluoride) (PVDF) is one of the most extensively practical highly organic selective materials in the industrial waste treatment due to its excellent thermal stability, biocompatibility as well as surpassing chemical and mechanical resistances. However, some severe disadvantages of PVDF such as the poor wettability and strong hydrophobicity properties as well as low surface energy perform as a barrier for the practical PVDF applicability and its further developments in aqueous solution systems. SBA-15-〖TiO〗_2/PVDF hybrid membranes with different nano-SBA-15-〖TiO〗_2 dosage were prepared via phase inversion method. The addition of Synthesized SBA-15-〖TiO〗_2 to PVDF as fillers could improve the properties of the membranes dramatically such as thermal property, contact angle, and permeability as well as the morphology and topography. The ability of effective removal of benzene has been demonstrated in several studies. The maximum percentage of removal happened at an optimized pH and reservoir solution around 7.0 and 400 mL, respectively. The modified membrane is suitable for organic compound treatment.
