Abstract
The present invention is a method utilizing a liquid-liquid contactor which employs an electrostatic field to mix an organic phase with an aqueous phase and to coalesce the aqueous phase in order to accomplish extraction of a component present in the aqueous phase. The electrostatic field is formed between a rod electrode located within a gaseous phase adjacent the top of the contactor and a plate electrode located within the aqueous phase adjacent the bottom of the contactor by applying a high voltage to the rod electrode. The extraction process consists of an extraction stage where the component is extracted out of the aqueous phase by the organic phase and a subsequent stripping stage where the component is stripped out of the organic phase by ion exchange with a second aqueous phase.
