Beschreibung
Zusammenfassung:	In one embodiment, the present invention relates to a process for recovering one of an onium hydroxide and onium salt from a solution containing an onium compound involving the steps of charging the solution containing the onium compound to an electrochemical cell comprising at least two compartments, a cathode, an anode, and a divider, wherein at least one compartment comprises an ion exchange material; passing a current through the electrochemical cell whereby the onium hydroxide or the onium salt is produced; and recovering the onium hydroxide or the onium salt from the electrochemical cell.
