What are the Assumptions for Ideal Extraction?

1. The Solvent and the carrier liquid are immiscible (mutually non-dissolving), this leads to complete recovery of carrier liquid in raffinate phase and complete recovery of extracting solvent in extract phase. 2. The Extraction Solvent Feed to the system is Pure (i.e. has no initial solute). 3. The Extract and Raffinate streams leaving the extraction stage are in equilibrium.

What is Liquid-Liquid Extraction?

Liquid–liquid extraction (LLE), also known as solvent extraction, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic. The transfer is driven by chemical potential, i.e. once the transfer is complete, the overall system of chemical components that make up the solutes and the solvents are in a more stable configuration (lower free energy). The solvent that is enriched in solute(s) is called extract. The feed solution that is depleted in solute(s) is called the raffinate.
