Different contents of magnetite nanoparticles (MNPs)/graphene (G) nanosheets were incorporated into polyvinyl alcohol (PVA) and cellulose acetate (CA) electrospun nanofibers. The obtained compositions were investigated using XRD, TEM, FTIR and FESEM. The microstructural investigation displayed that nanofibers were formed with diameters around 120 nm up to 900 nm in the case of the composition at 0.1MNPs-G/PVA, while morphological features illustrated that the composition at 0.0MNPs-G/PVA fibers was formed with diameters 0.2 mu m up to 0.6 mu m, besides G, which was scattered through the fibers with dimensions around 17 mu m. The removal efficiency of Se(IV) and Cr(VI) from aqueous solutions was evaluated and the optimum trend was obtained for the composition of 0.05MNPs-G@PVA. The high porous nanofibers may be suggested for more investigations for heavy metal removal.
