Abstract: The behavior of kinetic adsorption and desorption of two kinds of complexing adsorbents containing polyethylene polyamine,with Cu(Ⅱ) or Ni(Ⅱ) as the template ion for Cu(Ⅱ) and Ni(Ⅱ) respectively,was studied.The results of five operating cycles show that the complexing adsorbents possess stationary sorption capacity for Cu(Ⅱ) or Ni(Ⅱ).Its saturated sorption capacities for Cu(Ⅱ) and Ni(Ⅱ) are 4. 357 mmol Cu(Ⅱ)/g and 3.153 mmol Ni(Ⅱ)/g respectively.The relative errors are±1.5%and±2.2%respectively.
