Abstract
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 in conjunction with ion selective membranes; a two component cell employs cation permselective membranes to define acid and base compartments with the bipolar membranes, 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.
