ABSTRACT:
In one embodiment, the present invention relates to a process for recovering an organic hydroxide from waste solutions containing the organic hydroxide and impurities including the steps: contacting the waste solution with a metal ion scavenger to remove metal ion impurities; charging the waste solution to an electrochemical cell containing at least two compartments, a cathode, an anode and a divider and passing a current through the cell whereby the organic hydroxide is regenerated; and recovering the organic hydroxide from the cell.
