摘要: A novel antibacterial ultrafiltration (UF) membrane obtained by blending poly (vinylidene fluoride) (PVDF) with Ag+ exchanged NaY zeolite particles (AgNaY) was prepared using phase inversion methods. The AgNaY hybrid PVDF membranes exhibited excellent and long-lasting activity against Escherichia coli (E. coli). Its improved increased content. hydrophilicity of P-AgNaY-3 a low contact angle 81.6°. Compared P-0, the permeate performance, thermal stability, mechanical properties P-AgNaY were steady bovine serum albumin (BSA) retention above 92%. Antibacterial E. measured halo zone test. characterization AgNaY/PVDF investigated scanning electron microscope, X-ray diffraction, tensile stress tests, thermogravimetric analysis, pure water flux, permeation flux.
