以戊二醛为交联剂, 制备了壳聚糖(CS)-羧甲基纤维素(CMC)聚合物电解质膜. 用电子显微镜观察其表面形貌. IR分析表明该聚合物薄膜含有COOH, NH3+官能团, 具有两性离子的特征. 与CS膜或CMC膜相比, 该膜能稳定存在于酸碱溶液中. 膜特性研究表明CS-CMC聚合物电解质膜具有离子交换和选择性渗透能力, 可作为隔膜电解制备高铁酸盐.

The polyelectrolyte membrane was prepared by interaction between chitosan (CS) and carboxymethylcellulose (CMC) using glutaraldehyde as linkage reagent. SEM was used to observe its surface structure, while IR spectrum indicated that the polymer membrane has COOH and NH3+ functional groups and displays character of the amphoteric ion. Compared to CS or CMC membranes, CS-CMC membrane was stable in acid or alkali solution. The structure and properties were studied and the results show that the membrane can be used as a separator in electro-generation of FeO42-.
