Catalytic membrane contactor, Polyoxometalates, FT-IR, SEM, EDS analysis

In this study, 10-molybdo-2-vanadophosphoric (decamolydodivanadophosphoric) acid called POM having catalytic property, was initially synthesized and Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD) analyses were carried out. Afterwards, POM was modified to the commercial Polyvinylidene Fluoride (PVDF) membrane surface to produce a new catalytic membrane contactor (CMC). FT-IR, SEM, and EDS characterization of the CMC were performed to clarify that the POM was modified to the membrane. Then, contact angle, pure water fluxes and pore size of the CMC and unmodified PVDF membranes were analysed and compared. Consequently, according to FT-IR and EDS analyses, the CMC was produced successfully and according to contact angle results, this membrane has more hydrophilic than PVDF membrane. Moreover, when the pure water flux values were compared, the CMC fluxes were less than that of PVDF membrane
