Antiviral amphiphilic membranes based on the organometallic compound for protein removal from wastewater with fouling-resistant

Antiviral ultrafiltration membranes (UF) were successfully fabricated using amphiphilic polyvinylchloride-co-acrylic acid) (PVC-AA), which were incorporated with organometallic compound manganese acetylacetonate Mn(acac)3. Non-solvent induced phase separation (NIPS) method was used to prepare the UF membrane based on PVC-AA. Fabricated membranes were characterized by different analytical methods. The fabricated membranes (PVC-AA/ Mn(acac)3) provided the highest removal percentage for proteins when compared to the neat amphiphilic (PVC-AA). The hydrophilicity and antifouling properties of the membranes were improved with increasing load of manganese acetylacetonate Mn(acac)3 in the polymeric solution to 1%. The membrane with 1 wt% Mn(acac)3 (UF3) exhibited the best antifouling properties using bovine serum albumin 1 g.L−1and sodium alginate 2 g.L−1 and a real sample of wastewater namely ~ 99% of flux recovery ratio. PVC-AA- Mn(acac)3 provided antifouling and antiviral properties. The viral test using real sewage wastewater indicated that the membranes UF 2 and UF3 removes all viruses of 100%, which indicated negative detection in the treated water.
