探讨了交联魔芋葡甘聚糖和交联魔芋葡甘聚糖固化单宁微球的制备条件，进一步研究了新制的吸附剂一交联魔芋葡甘聚糖固化单宁微球对Sc^3＋的吸附性能，研究了时间、pH、温度和Sc^3＋的浓度等因素对材料吸附Sc^3＋的影响。结果表明：交联魔芋葡甘聚糖固化单宁微球对Sc^3＋的吸附在8h左右基本达到平衡，pH低于6．50时，Sc^3＋的平衡吸附量随pH和温度的升高而升高，50℃下，在HAc—NaAc介质中，当Sc^3＋的质量浓度为50mg／L，pH为6．39时，吸附容量达到886μg／g．

This study is dedicated to preparatory conditions of the cross-linked konjac glucomannan and its microspheres. Furthermore, the adsorptive property of the newly-prepared adsorptive--he konjac glucomannan microsphere-- to Sc^3＋ is put under discussion; the influence of factors like time, pH value, temperature and concentrations of Sc^3＋ to the adsorptive material are also subjected to examination. The results show that： the adsorption of the said microsphere to Sc^3＋ strikes a balance when the time length reaches about 8h; when the pH value drops below 6.5, the adsorbance rises with the rise of temperature and pH value. When the temperature drops below 50℃, and the concentration of Sc^3＋ is 50 mg/L and the pH value is 6.39, the adsorbance can reach 886μg/g in the media of HAc-NaAc, indicating that it has potential value in use in the Sc3＋ enriched field of separation.
