Abstract：

Ag3PO4/TiO2　nanocomposite　was　fabricated　by　an　in　situ　precipitation　method　and　then　blended　into　poly(vinylidene　fluoride)　(PVDF)　casting　solution　to　prepare　the　ultrafiltration　membrane　via　wet　phase　inversion　technique.　The　water　flux　and　bovine　serum　albumin　(BSA)　rejection　rate　of　membrane　were　investigated;　meanwhile,　the　ultrafiltration　membrane　morphologies　and　structural　properties　were　analyzed　using　scanning　electron　microscope　(SEM)　and　X-ray　diffraction.　Compared　with　the　control　membrane,　the　permeate　performance　of　blended　membranes　was　improved　while　possessing　a　steady　BSA　retention　due　to　enhanced　hydrophilicity.　Mechanical　tests　revealed　that　the　modified　membranes　exhibited　a　larger　tensile　strength　and　breakage　elongation.　SEM　images　and　the　halo　zone　testing　were　employed　to　assess　the　antibacterial　performances　of　the　nanocomposite　membranes　against　Escherichia　coli.　The　antibacterial　tests　confirmed　that　the　modified　membranes　showed　an　effective　antibacterial　property　against　E.　coli.　©　2017　Desalination　Publications.　All　rights　reserved.
