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 Solute from Activity Coefficient?
Distribution Coefficient of Solute from Activity Coefficient calculator uses Distribution Coefficient of Solute = Activity Coefficient of Solute in Raffinate/Activity Coefficient of Solute in Extract to calculate the Distribution Coefficient of Solute, The Distribution Coefficient of Solute from Activity Coefficients of the Solute formula is defined as the ratio of activity coefficients of the solute in the raffinate phase to that in the extract phase. Distribution Coefficient of Solute is denoted by KSolute symbol.
How to calculate Distribution Coefficient of Solute from Activity Coefficient using this online calculator? To use this online calculator for Distribution Coefficient of Solute from Activity Coefficient, enter Activity Coefficient of Solute in Raffinate (ΥcR) & Activity Coefficient of Solute in Extract (ΥcE) and hit the calculate button. Here is how the Distribution Coefficient of Solute from Activity Coefficient calculation can be explained with given input values -> 2.6 = 4.16/1.6.
