What is the principle behind solvent extraction? The principle behind solvent extraction is extremely basic. The goal is to use a liquid (solvent) to dissolve (solvate) a target molecule or group of compounds (solute) and to wash them out of the solid plant material. The solvent is then separated from the solute in order to concentrate the solute.
What is the principle behind Liquid Liquid Extraction? Liquid–liquid extraction (LLE) is based on the principle that a solute or an analyte can distribute itself in a certain ratio between two immiscible solvents, usually water (aqueous phase) and organic solvent (organic phase).
What is the principle of extraction process? Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. Common examples include liquid-liquid extraction, and solid phase extraction. The distribution of a solute between two phases is an equilibrium condition described by partition theory.
