| 摘 要： | 利用无毒交联剂制备壳聚糖微球并负载稀土元素,制得新型除氟吸附剂。配制水除氟实验中,Ce-CEB对F^-(纯NaF溶液)的静态吸附容量为17.7 mgF^-/g微球,F^-的脱除率为93.4%;对于具有复杂阴离子的配制水,Ce-CEB对F^-的动态饱和吸附量为12.3 mgF^-/g微球。

| Abstract: | A novel defluorination adsorbent was prepared by preparing chitosan microspheres with non-toxic cross-linking agent and loading rare earth element. In the fluoride removal experiment with prepared water, the static adsorption capacity of Ce-CEB for F^- (pure NaF solution) was 17. 7 mgF^-/7g microsphere, and the removal rate of F^- was 93.4%. For the prepared water with complex anions, the dynamic saturation adsorption capacity of Ce-CEB for F^- was 12. 3 mgF^-/7g microspheres. |
