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%。
The dynamic adsorption of metal ions on copper (Ⅱ) and nickel (Ⅱ) ion template poly (ethylene polyamine) complex adsorbents was studied. The results of five cycles showed that the adsorbents of copper (Ⅱ) and nickel (Ⅱ) have stable adsorption capacity to copper (Ⅱ) and nickel (Ⅱ) metal ions respectively and their dynamic adsorption capacity reaches 4. 357 mmol Cu (Ⅱ) / g [copper (Ⅱ) template adsorbent] and 3.153 mmol Ni (Ⅱ) / g [nickel (Ⅱ) template adsorbent] with relative errors of ± 1.5% and ± 2.2%, respectively.
