What is Selectivity or Separation Factor?

The effectiveness of solvent B for separating a solution of A and C into its components measured by comparing the ratio of C to A in the B rich phase to that in the C rich phase at equilibrium and is called selectivity or separation factor. This is also analogous to relative volatility in distillation. Selectivity of the solute varies with the compositions of the two phases in equilibrium and depends upon temperature. It is unit at the Plait point at the compositions of the two phases becomes the same. It is preferable to use a solvent with selectivity higher than unity, though in some systems it varies from higher values to unity to fractional values. These systems are analogous to azeotropes.

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.
