Haponiuk, Sreeraj GopiAbstractBionanocomposites prepared from green sources are a promising research area and cellulose nanofibers obtained from agro-waste of ginger rhizomes and their different composites with starch, chitosan (CS) and polyvinyl alcohol (PVA) have exhibited enormous mechanical as well as antimicrobial properties. This paper reports the synthesis of magnetic ginger nanofiber (M-GNF) reinforced composite films with CS, PVA and potato starch (PS) by Fe3O4 nanoparticles by in-situ co-precipitation method. These magnetic composite films were prepared by simple casting method and the magnetic properties were analysed by magnetic susceptibility measurements using Vibrating Sample Magnetometer (VSM), surface morphology and structural analysis were analysed by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), Differential scanning calorimetry (DSC) and X-ray diffraction (XRD) methods. The magnetic composites incorporated with GNF were thermally stable, mechanically strong, insoluble in water and easily removable from water by external magnetic field. These magnetic composites were explored as an adsorbent for removing copper (II) ions from aqueous solution and the M-GNF-CS composite exhibited highest effectiv...
