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.
How to Calculate Distribution Coefficient of Carrier Liquid from Activity Coefficients?
Distribution Coefficient of Carrier Liquid from Activity Coefficients calculator uses Distribution Coefficient of Carrier Liquid = Activity Coefficient of Carrier Liq in Raffinate/Activity Coefficient of Carrier Liquid in Extract to calculate the Distribution Coefficient of Carrier Liquid, The Distribution Coefficient of Carrier Liquid from Activity Coefficients formula is defined as the ratio of activity coefficients of the carrier liquid in the raffinate phase to that in the extract phase. Distribution Coefficient of Carrier Liquid is denoted by KCarrierLiq symbol.
