    摘要: In one embodiment, the present invention relates to a process for recovering an onium hydroxide from a solution containing an onium compound, including contacting the solution with a cation exchange material so that at least a portion of onium cations from the onium compound are adsorbed by the cation exchanger material; contacting an acid with the cation exchanger material to elute an onium salt; charging the onium salt to an electrochemical cell (10) containing at least two compartments (14 and 15), a cathode (12), an anode (11), and an anion selective membrane (13) therebetween, and passing a current through the cell whereby the onium hydroxide is regenerated.
