CS-CMC bipolar membrane was prepared and the cross-section photograph of CS-CMC BM was observed by SEM. FT-IR spectrum indicated that CS-CMC BM contained -N=CRH₂+and -COO^- functional groups. The charge density of -N=CRH₂⁺ in CS membrane was about 14.13 mmol/g and the charge density of -COO^- in CMC membrane was about 9.01 mmol/g. The electrochemistry properties of CS-CMC BM were also studied. CS-CMC BM not only can effectively stop FeO₄^2- from diffusing into the cathode chamber, but also plays an important role in the supply of OH^- consumed during the electro-generated FeO₄^2- process.
