壳聚糖基吸附剂的制备及其对铀的吸附性能研究OA北大核心
Study on Synthesis and Adsorption Behavior for Uranyl of Chitosan-based Adsorbents
借助化学改性手段合成了以壳聚糖为骨架的胺基生物高分子吸附剂，利用红外光谱、胺基含量测定等方法表征了聚合物的结构。考察了溶液pH、吸附剂的胺基修饰、交联剂用量等对壳聚糖吸附剂吸附铀的性能的影响。结果表明：以三乙烯四胺改性的壳聚糖基吸附剂CATT对铀具有较高吸附容量，对低浓度溶液中铀的去除率大于94％；所合成的生物高分子吸附剂有望解决铀湿法冶金工艺中含铀废水处理工艺复杂、原材料成本相对较高等问题。
