چکیده

Using interfacial polymerization (IP) of m-phenylenediamine aqueous solution
containing polyoxovanadate nanoclusters (POV) and trimesoyl chloride (TMC)
in organic solution, we fabricated a novel polyamide (PA)- polyoxovanadate
nanocluster (POV) nanocomposite membranes (PA-POV TFN). The chemical
structures and morphologies of the synthesized membranes were characterized
by Fourier transform infrared (FTIR) spectroscopy, atomic force microscope
(AFM), scanning electron microscopy (SEM) and water contact angle measurements.
Experimental results showed that the performances of PA-POV TFN
membranes are remarkably dependent on POV incorporation in the membranes,
which could be controlled by using different amounts of POV particles.
Moreover, the PA-POV TFN membranes illustrated outstanding antibacterial
properties against Gram-negative E. coli. On the other hand, the incorporation
of various amounts of POV in the membranes improved the membrane separation
performances (water flux and salt rejection) as well as the antibacterial
activity in FO process as compared to the original thin-film composite (TFC)
polyamide membrane.
