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

Poedji Loekitowati Hariani; Fahma Riyanti

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.
