UV-Vis adsorption studies of Nickel-Cobalt ferrite developed by combustion method

Abstract

Present work deals with the synthesis of magnetic Nickel-Cobalt spinel ferrite [Ni0.5Co0.5Fe2O4] nanoparticles using combustion method, and adsorption of different dyes using synthesized ferrite material. Synthesized ferrite material has been characterized by using FTIR spectroscopy. Nickel-Cobalt ferrite material has worked very efficiently as an adsorbent and can absorb different dyes from their aqueous solutions. Its magnetic nature gives a fair chance to extract it back from the solutions, by applying magnetic field. Extracted ferrite materials don't lose its potency to adsorb. Hence, it can be used in number of wastewater treatment cycles. Adsorption capacity and reusability of these ferrite materials make them suitable for future alternate adsorbents in the field of wastewater treatment.
