  • Liquid-Liquid Extraction - an overview ScienceDirect

    Liquid-liquid extraction, also known as partitioning, is a separation process consisting of the transfer of a solute from one solvent to another, the two solvents being immiscible or partially miscible with each other. Frequently, one of the solvents is water or an aqueous mixture and the other is a nonpolar organic liquid.
