PROCESS FOR RECOVERING ONIUM HYDROXIDES OR ONIUM SALTS FROM SOLUTIONS CONTAINING ONIUM COMPOUNDS USING ELECTROCHEMICAL ION EXCHANGE

摘要

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 (10) comprising at least two compartments (14 and 15), a cathode (12), an anode (11), and a divider (13), 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.
