ABSTRACT:
A process for regenerating spent seed materials used in magnethohydrodynamic power generation, such materials comprising an alkali metal carbonate and an alkali metal sulfate as the contaminant which process comprises the steps of introducing an aqueous solution of the spent seed materials into the acid zone of an electrodialysis cell, introducing an aqueous solution of carbon dioxide, an alkali metal carbonate, an alkalimetal bicarbonate or mixture thereof into the base zone of the cell, and thereafter passing a direct current through the cell producing an alkali metal carbonate in the base zone and an alkali metal bisulfate or sulfuric acid in the acid zone.
