The characterization of nanocomposite membranes
Fourier transform infrared spectrum
Fourier transform infrared (FTIR) spectrum was used in order to
prove the presence of Fe3O4 nanoparticles in the structure of PSf membrane (BRUKER, Model: TENSOR 27, Germany). For making the membrane samples thin and transparent, they were put under the high
pressure (14 bar), and then were analyzed
