Abstract

The sugar cane bagasse fly ash is a waste material generated in bagasse combustion used in energy generation for sugar and ethanol production in Brazilian (SBA1) and Cuban (SBA2) industries. Sugar cane bagasse fly ashes from specific regions in each country have been tested as adsorbent materials in Ni (II) ions removal. The adsorbents were characterized using X-Ray Fluorescence, Fourier Transformed Infrared Spectroscopy (FTIR) and X-Ray Diffraction techniques. The kinetic study showed that the equilibrium system in Ni (II) ions removal was reached in 40 minutes. The maximal adsorption capacity values obtained were 1,21 mg g-1for SBA1 and 1,80 mg g-1for SBA2. The kinetic data behavior was of pseudo second order. The equilibrium study allowed concluding that Ni (II) ions removal process isotherms using SBA1 and SBA2 had a better fitting to Langmuir and Toth model.
