摘　　要：报道了影响活性二氧化锰对Fe^(++)离子吸附性能的几种重要因素并逐项进行了研究,分别确定了3个温度下Freundlich经验式中的几个常数,并发现吸附量随活化温度的变化与吸附剂比表面随温度变化趋势完全一致,并与电解MnO_2,β-MnO_2的变化趋势作了对比。最后,为吸附Fe^(++)离子的活性MnO_2,选择了最佳脱附条件。The factores of affecting absorbability of active manganese dioxide for Fe^(2-) ions in water have been discussed. The relation between absorbable quality of absorbent and Fe^(2+) ions concentration in aqueous obeys Freundlich isotherm. With increasing active temperature, the changing tendency of absorbable quality of absorbent tends to be consistent with that of specific surface for absorbent, and is in comparision with that of eletrolytic MnO_2 and β MnO_2. Finaly, the optimal condition of Fe^(2+) ions desorption from adsorbent have been selected.
