ELECTRODIALYTIC WATER SPLITTING PROCESS FOR THE TREATMENT OF AQUEOUS ELECTROLYTES

摘要

A process for dealkalization or acidification of aqueous salt solutions or for the splitting of the salt of such solutions employs a water splitting system of bipolar membranes (3) in conjunction with ion selective membranes (2); a two-compartment cell employs cation permselective membranes (2) to define acid and base compartments with the bipolar membranes (3), and a three compartment cell employs anion permselective and cation permselective membranes to define with the bipolar membrane salt, acid and base compartments; the process has particular applicability to the dealkalization of a monosodium peroxide solution containing sodium hydroxide produced in a hydrogen peroxide generator.
