Magnetic CuFe₂O₄ Nanoparticles for Adsorpstion of Cr(VI) from Aqueous Solution

Abstract:

CuFe₂O₄ nanoparticles were synthesized by co-precipitation method from the solution of CuCl₂ and FeCl₃ in alkaline condition. The prepared magnetic CuFe₂O₄ can be used to adsorb Cr (VI) ions from aqueous solution and separated from medium by magnetic technique. The characterization of CuFe₂O₄ with X-Ray diffraction (XRD) showed cubic units shells with diameter in the range 15-20 nm which obtained by Transmission Electron Microscope (TEM). The saturation of magnetization is around 13 emu g^-1 measured with Vibrating Sample Magnetometer (VSM). Batch adsorption studies were carried out to optimize adsorption condition. Effective conditions for adsorption of Cr (VI) were found at the weight of CuFe₂O₄ was 1.0 g with contact time of 60 minutes and pH 3 with adsorption capacity 9.20 mg g^-1.
