摘要： 研究了铜(Ⅱ)、镍(Ⅱ)离子模板高分子多乙烯多胺络合吸附剂的动态吸附金属离子的行为。5个周期的动态吸附结果表明,合成的铜(Ⅱ)、镍(Ⅱ)模板吸附剂分别对铜(Ⅱ)和镍(Ⅱ)金属离子具有稳定的吸附能力,其动态饱和吸附量达4.357mmolCu(Ⅱ)/g[铜(Ⅱ)模板吸附剂]、3.153mmolNi(Ⅱ)/g[镍(Ⅱ)模板吸附剂];相对误差分别为±1.5%和±2.2%.

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.
