Abstract:
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.
