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 Mole Fractions?
Selectvity of Solute based on Mole Fractions calculator uses Selectivity = (Mass Fraction of Solute in the Extract/Mass Fraction of Carrier Liquid in the Extract)/(Mass Fraction of Solute in the Raffinate/Mass Fraction of Carrier Liquid in the Raffinate) to calculate the Selectivity, The Selectvity of Solute based on Mole fractions formula is defined as the ratio of mole fraction of solute in extract to carrier liquid in extract to that of the solute in raffinate to carrier liquid in raffinate. Selectivity is denoted by βC, A symbol.
How to calculate Selectvity of Solute based on Mole Fractions using this online calculator? To use this online calculator for Selectvity of Solute based on Mole Fractions, enter Mass Fraction of Solute in the Extract (yC), Mass Fraction of Carrier Liquid in the Extract (yA), Mass Fraction of Solute in the Raffinate (xC) & Mass Fraction of Carrier Liquid in the Raffinate (xA) and hit the calculate button. Here is how the Selectvity of Solute based on Mole Fractions calculation can be explained with given input values -> 1.818572 = (0.3797/0.674)/(0.1394/0.45).
