The paper reports on the preparation of polysiloxane hydrophobized viscose-maghemite/goethite magnetic composite with properties appropriate for uses in oil spill sorption from polluted aqueous media. A multi-step procedure was employed to obtain the polymeric composite. The structures of the prepared samples and precursors were analyzed by Fourier transform infrared spectroscopy (FTIR), whereas their morphology was investigated by means of scanning electron microscopy (SEM). The hydrophobic...
