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 Selectvity of Solute based on Activity Coefficients?
Selectvity of Solute based on Activity Coefficients calculator uses Selectivity = (Activity Coefficient of Solute in Raffinate/Activity Coefficient of Solute in Extract)/(Activity Coefficient of Carrier Liq in Raffinate/Activity Coefficient of Carrier Liquid in Extract) to calculate the Selectivity, The Selectvity of Solute based on Activity Coefficients formula is defined as the ratio of activity coefficiens of solute in raffinate to carrier liquid raffinate to that of the solute in extract to carrier liquid in extract. Selectivity is denoted by βC, A symbol.
How to calculate Selectvity of Solute based on Activity Coefficients using this online calculator? To use this online calculator for Selectvity of Solute based on Activity Coefficients, enter Activity Coefficient of Solute in Raffinate (ΥcR), Activity Coefficient of Solute in Extract (ΥcE), Activity Coefficient of Carrier Liq in Raffinate (ΥaR) & Activity Coefficient of Carrier Liquid in Extract (ΥaE) and hit the calculate button. Here is how the Selectvity of Solute based on Activity Coefficients calculation can be explained with given input values -> 1.733333 = (4.16/1.6)/(1.8/1.2).
