摘要

本研究旨在通过使用 TiO2-AgBr-Ag-SBA-15 改性聚醚砜(PES)聚合物膜,提高其渗透性和防污性能。采用水热法制造二氧化硅纳米颗粒(SBA-15),其中包括使用四乙基正硅酸盐作为前驱体和共聚物 Pluronic P123(作为模具和溶剂排出后的结构保持剂)。然后,在 TiO2-AgBr-Ag 的制备溶液中加入 SBA-15 纳米粒子,最后在浇铸溶液中加入掺杂纳米粒子(TiO2-AgBr-Ag-SBA-15),使最终膜的重量百分比分别达到 0.4、0.6、0.8 和 1。使用 FESEM、FT-IR、XRD、XPS 和 EDX 对纳米颗粒进行了表征。同时,利用 FESEM、FT-IR、CA、AFM 和膜性能测试研究了膜的特性。混合膜的表面疏水性较低,因此透水性较好。此外,膜的防污性能也得到了显著改善,从而在不影响膜去除有害物质能力的情况下大大提高了透水性。在 3.5 巴压力下,0.8 wt% PES/TiO2-AgBr-Ag-SBA-15 膜的纯水通量是原始膜的两倍。1 wt% PES/TiO2-AgBr-Ag-SBA-15 膜的通量回收率可达 90%,防污性能优异。

Fabrication of novel polyethersulfone (PES) photocatalytic membranes with excellent permeability and antifouling properties using TiO2–AgBr–Ag–SBA-15 nanofillers for cefixime removal

This study aimed to enhance the permeability and antifouling properties of the polymer membrane of polyethersulfone (PES) through the modification with TiO2–AgBr–Ag–SBA-15. The hydrothermal process is used to create silica nanoparticles (SBA-15), which involved the use of tetraethylorthosilicate as a precursor and a copolymer Pluronic P123 (as a mold and the structure maintainer after solvent exiting). Then, SBA-15 nanoparticles are added to the preparation solution of TiO2–AgBr–Ag, resulting doping nanoparticles (TiO2–AgBr–Ag–SBA-15) were incorporated into the casting solution to achieve weight percentages of 0.4, 0.6, 0.8 and 1 in the final membranes. The nanoparticles were characterized using FESEM, FT-IR, XRD, XPS and EDX. Meanwhile, the membrane properties were studied using FESEM, FT-IR, CA, AFM and membrane performance tests. The hybrid membranes exhibited a less hydrophobic surface, which consequently resulted in water permeability. Moreover, the antifouling properties were notably improved, resulting in a considerable improvement in permeability without compromising the membrane's ability to remove unwanted substances. At 3.5 bar pressure, the pure water flux of the 0.8 wt% PES/TiO2–AgBr–Ag–SBA-15 membrane was two times higher than that of the pristine membrane. Flux recovery rate of 1 wt% PES/TiO2–AgBr–Ag–SBA-15 membrane can reach 90%, and the antifouling performance is excellent.
