| Abstract | The removal of Copper (Cu), Zinc (Zn), Nickel (Ni) and Cobalt (Co) from aqueous solutions by adsorption onto natural bentonite was investigated. Experiments were carried out as a function of shaking time, temperature of solution and thermal treatment of bentonite. The kinetic processes of metal ions adsorption on bentonite were described by applying pseudo-first order and pseudo-second order rate equations. The pseudo-second order reaction rate model was found to describe best the kinetic data. The thermodynamic parameters (ΔH, ΔS and ΔG) for Copper (Cu), Zinc (Zn), Nickel (Ni) and Cobalt (Co) adsorption onto bentonite were also determined from the temperature dependence. The adsorption was endothermic reactions for Copper (Cu) and Zinc (Zn), and exothermic for Nickel (Ni) and Cobalt (Co). The results suggested that natural bentonite is suitable as an adsorbent material for adsorption of metal ions from aqueous solutions. |
