Development of ZnFeCe Layered Double Hydroxide Incorporated Thin Film Nanocomposite Membrane with Enhanced Separation Performance and Antibacterial Properties

Developing thin-film nanocomposite (TFN) membranes by incorporating nanomaterials into the selective polyamide (PA) layer is an effective strategy to improve separation and antibacterial properties. In this study, TFN nanofiltration (NF) were fabricated interfacial polymerization of piperazine (PIP) trimesoyl chloride (TMC) with addition Zinc-Iron-Cerium (ZnFeCe) layered double hydroxide (LDH). The improved surface hydrophilicity was investigated water contact angle analyses pure flux measurements. Successful production PA on membrane determined Fourier-transform infrared (FTIR) analysis. Atomic Force Microscope (AFM) images showed that LDH resulted in a smoother surface. scanning electron microscope energy-dispersive X-ray spectroscopy (SEM/EDS) mapping proved presence Ce, Fe, Zn elements, indicating successful nanoparticles 3 characterized highest resulting 161% enhancement compared pristine thin film composite (TFC) membrane. All great rejection performances (with higher than 95% 88% for Na2SO4 MgSO4, respectively) divalent ions. Additionally, exhibited excellent self-cleaning properties TFC
