Description

Technical Field

[0001] The present invention relates to a separator, in particular to a bipolar membrane electrodialysis separator, belonging to the technical field of bipolar membrane electrodialysis. Background Art

[0002] The bipolar membrane is composed of an anion exchange resin layer (AL), a cation exchange resin layer (CL), and an intermediate catalytic layer. Under the action of a DC electric field, the H2O between the anion and cation exchange membrane composite layers dissociates into H+ and OH-. These pass through the cation and anion membranes, respectively, acting as sources of H+ and OH- ions. The bipolar membrane can directly dissociate water into H+ and OH-, thereby achieving a splitting decomposition of inorganic salts to produce the corresponding acids and bases.
