Liquidliquid extraction also known as solvent extraction involves the separation of the constituents solutes of a liquid solution by contact with another insoluble liquid. Liquidliquid 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. This is illustrated for the determination of thiopental in serum and plasma 6.
