摘　　要：以Fe3+为交联剂,制备了阳离子聚丙烯酰胺(CPAM)-羧甲基纤维素(CMC)聚合物电解质膜.用红外光谱和扫描电镜对其成分与形态进行了表征,并将其应用于电解制备高铁酸盐.实验结果表明,CPAM-CMC聚合物电解质膜能有效地阻止FeO42-向阴极室扩散,同时阴极室中生成的OH-及时地补充了阳极室中OH-的消耗.The polyelectrolyte membrane was prepared by interaction between cation polyacrylamide and carboxymethylcellulose using Fe3+ as linking reagent.CPAM-CMC membrane was characterized by FTIR and SEM,and applicated in electro-generated ferrate.The experimental results showed that CPAM-CMC membrane was available in preventing FeO42-expanding to cathode chamber and supplying OH-in anode chamber in time from cathode chamber.
