The　β-cyclodextrin　modified　MoS2　tubular　ceramic　composite　membrane　was　prepared　by　in-situ　hydrothermal　method　on　the　surface　of　alumina　ceramic　substrate　with　β-cyclodextrin　(β-CD)　as　an　additive　into　precursor　solution.　The　surface　morphology,　structure,　chemical　composition,　hydrophilicity　and　charge　of　the　membrane　were　well　investigated　by　search　engine　marketing,　X-raydiffraction,　X-ray　photoelectron　spectroscopy,　water　contact　angle　and　zeta　potential　techniques.　The　effect　of　different　β-CD　amount　on　the　membrane　nanofiltration　performance　as　well　as　the　pressure　resistance　and　long-term　stability　of　the　membranes　were　studied.　The　results　indicated　that　the　permeability　of　the　membrane　was　greatly　increased　due　to　that　the　cavity-related　structure　of　β-CD　provided　additional　fast　transport　channels　for　water　molecules.　When　the　amount　of　β-CD　was　2.4%,　the　water　permeability　of　the　membrane　was　highest　as　325L/(m2·h·MPa)　along　with　98.6%　rejection　of　Evans　blue　(EB),　and　more　than　90%　rejection　for　chrome　Black　T　(EBT)　and　Xylenol　orange　(XO).　The　prepared　membrane　showed　an　excellent　pressure　resistance　at　0.2—0.8MPa　pressure　and　displayed　a　great　long-term　stability.　©　2023　Chemical　Industry　Press.　All　rights　reserved.
