| 摘 要： | 以F eC l3改性羧甲基纤维素(CM C),使得水溶性CM C膜改性为疏水性阳离子交换膜CM C-F e,该膜能稳定存在于酸碱溶液中.用扫描电镜观察其表面形态,IR分析表明改性羧甲基纤维素中的-COOH吸收峰发生了位移.将其应用于电渗析去除高浓度氨氮废水的处理中,结果表明,该膜对氨氮的选择透过性较好,能有效地去除水中氨氮,去除率可达90%.NH4 的迁移过程符合一级反应动力学.

| Abstract: | An insoluble CMC-Fe membrane was prepared by being linked soluble carboxymethyl-cellulose with FeCl_3.The membrane as a cationic exchanging membrane in electrodialysis was applied in treating wastewater with high concentration of inorganic ammonia and azote.The results of experiment showed that it was well-selective to ammonia and azote.The percentage of the removal of ammonia and azote in wastewater is up to 90%.The migration process of NH_4~ is following one class reaction kinetics. |
