| Abstract: | Ni(II) imprinted and non-imprinted bioadsorbent alginate beads were prepared, and utilized in the selective adsorption of Ni(II) ions. The optimum adsorption capacity were 6.00 mmol g?1 at 500 ppm initial metal ion concentration at pH 7 for Ni(II) imprinted alginate beads (IIP). The equilibrium data were applied to Langmuir and Freundlich adsorption isotherms, and it fitted both isotherm models. Thermodynamic parameters showed favorable and endothermic nature of adsorption. Ni(II) imprinted bead showed the strong ability to selective adsorption from Cu(II), Co(II) and Zn(II) ions. In conclusion, Ni(II) ion imprinted alginate beads could be used repeatedly without any significant reduce of adsorption capacity. |
