Abstract :In this study, polyvinylidene fluoride insert ignore into journalissuearticles values(PVDF); polymeric membranes with addition of functionalized carbon-based material insert ignore into journalissuearticles values(CBM); were fabricated by using electrospinning technique for the removal of cationic dyes from wastewater. CBM was prepared through a two-step carbonization process from cotton linter as an agricultural waste biomass. The characterization of CBM was performed by using Brunauer–Emmett–Teller insert ignore into journalissuearticles values(BET); surface analysis, fourier transform infrared spectrometry insert ignore into journalissuearticles values(FTIR); and elemental analysis. The morphologies of electrospun membranes were observed by scanning electron microscope insert ignore into journalissuearticles values(SEM); which clearly revealed that nanofibers with a smooth surface were produced by incorporation of CBM. According to the results obtained from FTIR and differential scanning calorimetry insert ignore into journalissuearticles values(DSC);, crystallization behavior of PVDF membranes was promoted by increasing the percentage of CBM in the membrane. PVDF membrane prepared with the addition of 3 wt % CBM exhibited the highest water flux performance with a dye rejection of 74.6 % in comparison with the pure PVDF one.
