ABSTRACT:
A process for removing an ionic impurity from an impure substantially non-aqueous liquid passes the impure non-aqueous liquid through at least one ion exchange compartment containing an ion exchange medium. The ion exchange compartment is separated from an anode compartment and a cathode compartment by ion exchange membranes, where the ion exchange membranes and ion exchange medium having functional groups of the opposite charge as that of the ionic impurity. An electric current is conducted across the ion exchange compartment substantially transverse to the direction of flow of the impure non-aqueous liquid, and transporting the ionic impurity through an ion exchange membrane to separate the ionic impurity from the non-aqueous liquid.
