Abstract :
The present paper deals synthesis of polyvinyl pyrrolidone (PVP)-coated magnetite nanoparticles by chemical co-precipitation method. The samples were characterized using X-ray difraction, scanning electron microscopy, energy-dispersive X-ray
spectroscopy (EDX), Fourier transform infrared spectroscopy (FT-IR) and Brunauer–Emmett–Teller (BET) methods. The
surface area, pore volume and pore radius were calculated by the BET analysis. The EDX and FT-IR analysis demonstrated
the fabrication of PVP-coated Fe3O4 NPs. The as-synthesized Fe3O4/PVP has successfully been used as an adsorbent for
elimination of Congo red dye in aqueous medium.
