Abstract

CuFe2O4-bentonite composite successfully synthesized using chemical co-precipitation method and using to adsorp Ni(II) from electroplating wastewater. The composite was characterized by Fourier Transform Infra Red and Scanning Electron Microscope-Energy Dispersive X Ray Spectroscopy. The FTIR spectra of CuFe2O4-bentonite composite presented the characteristic of CuFe2O4 and bentonite. Typical of bentonite obtained by the bands at 1033.8 cm-1 correspondent to the intensity of Si-O. The observed two peaks at 432.0 cm-1 and 536.2 cm-1 attributed to the tetrahedral and octahedral of CuFe2O4. The result indicated that CuFe2O4 particles deposited on the surface of bentonite. The main component of CuFe2O4-bentonite composite contained of CuFe2O4 and bentonite from EDX spectra. Batch experiments were carried out to investigate optimum condition of adsorption Ni(II) onto CuFe2O4-bentonite composite. The optimum condition for initial concentration of Ni(II) 50 mg L-1 and volume 50 mL obtained at weight of CuFe2O4-bentonite composite of 100 mg, contact times at 60 minutes and pH of the solution 5. The adsorption efficiency of Ni(II) from electroplating wastewater using CuFe2O4-bentonite composite at optimum condition was 99.136 %, respectively
