Bipolaariset tarkkuusmembraanit, niiden valmistusmenetelmä ja käyttö

摘要

A low electrical resistance bipolar membrane formed by the conjoining of treated anion and cation exchange membranes is disclosed. The treatment comprises contacting the membranes with an aqueous solution of at least one cation prior to conjoining and contacting at least one face of the membranes with an aqueous alkaline solution. A process for the preparation of acid and alkali using these bipolar membranes is also disclosed.
