Magnetically enhanced phase separation for solvent extraction

Abstract

Briefly, the invention provides a method for magnetically assisting demulsification of extraction phases, the method having the steps of contacting a first solution of a first solvent and a solvated paramagnetic metal ion with a second solvent, where the second solvent is immiscible with the first solvent; mixing the first and second solutions to create an emulsion having a first phase of the first solvent and second phase comprising the second solvent where the phases of the emulsion contain different concentrations of the paramagnetic metal ion; and applying a magnetic field gradient to the first and second phases of the emulsion to accelerate separation of the first phase from the second phase. Also provided is a system for demulsifying phases used in the extraction of paramagnetic moieties from solution having a lumen with an interior region, an interior surface, and exterior surface; and a magnetic field gradient present within the interior region.
