<p>An acid or base is generated in an aqueous solution by the steps of: (a) providing a source of first ions (40) adjacent an aqueous liquid in a first acid or base generation zone (50), separated by a first barrier (46) (e.g., anion exchange membrane) substantially preventing liquid flow and transporting ions only of the same charge as said first ions, (b) providing a source of second ions of opposite charge (40) adjacent an aqueous liquid in a second acid or base generation zone (48), separated by a second barrier (44) transporting ions only of the same charge as the second ions, and (c) transporting ions across the first barrier by applying an electrical potential (52, 54) through said first and second zones and a base-containing aqueous solution in the other one which may be combined to form a salt (62). Also electrolytic apparatus for performing the above method. The product solutions can be used as an element for a chromatographic separation medium (70). The element can be regenerated in order to reuse the ions by means of a membrane suppressor (74).</p> |
