Abstract
Ions are electrochemically removed from an aqueous solution by establishing an electrochemical cell wherein the solution, as cell electrolyte, is caused to flow between a working electrode that includes an ion exchange material and a second electrode that optionally includes an ion exchange material. The polarity of the cell is repeatedly reversed so that ions are successively adsorbed and desorbed at the working electrode and optionally also at the second electrode. Thus, an ion for removal such as Cs.sup.+ may be selectively removed in the presence of a much larger concentration of a second ion such as Na.sup.+.
