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-.

Key words: polyelectrolyte, chitosan, carboxymethylcellulose, glutaraldehyde, ferrate, electrolyte
