Abstract
A method for processing multi-phasic dispersions is provided. The method comprises providing a multi-phasic dispersion including dispersed and continuous phases, providing one or more non-solvents comprising an aqueous solution containing at least one multivalent cation, exposing the multi-phasic dispersion to the non-solvent to form a suspension containing one or more liquid phases and the solid microparticles, and removing at least a portion of the resulting one or more liquid phases while retaining at least the microparticles, thereby removing at least a portion of the non-volatile material from the microparticles.
