首先采用液相氧化沉淀法制备氧化高银粉末,再通过相转化法制备氧化高银醋酸纤维素膜。研究了氧化高银质量分数对膜分离性能和抗菌性的影响。并通过X射线衍射(XRD)分析氧化高银相结构,并采用扫描电子显微镜(SEM)对氧化高银醋酸纤维素膜表面形貌进行表征;并通过膜性能评价仪测试膜的分离性能;抑菌圈法测试膜对枯草芽孢杆菌的抗菌性。结果表明:氧化高银最佳添加质量分数量为0.5%,制备的膜具有抗菌性,且其水通量达97.39 L/(m2·h)。 Firstly, oxidized high silver powder was prepared by liquid phase oxidation and precipitation, and then oxidized high silver acetate film was prepared by phase inversion method. The effects of the mass fraction of oxidized high silver on the membrane separation performance and antibacterial activity were studied. The structure of the oxidized high silver phase was analyzed by X-ray diffraction (XRD), and the surface morphology of the oxidized high silver acetate cellulose film was characterized by scanning electron microscopy (SEM). The separation performance of the film was tested by membrane performance analyzer. Bacteriostatic test membrane antimicrobial Bacillus subtilis. The results showed that the best addition mass fraction of high silver oxide was 0.5%, and the prepared membrane was antibacterial with a water flux of 97.39 L / (m2 · h).
