Liquid–liquid extraction Wikipedia

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, 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.

What is Solvent Extraction and Why is it Important?

Solvent extraction has always proved itself very helpful as a recovery method for many components. It is a method of separating compounds on the basis of their solubility in two different immiscible liquids like water and organic compound.

What is Solvent Extraction? (with pictures)

22/11/2019· Solvent extraction is a method for separating a substance from one or more others by using a solvent. It relies on variations in the solubilities of different compounds in different substances. In most cases, the substance to be extracted, which may be a solid, a liquid or a gas, is dissolved in a liquid, along with other substances, and a liquid solvent is used for the extraction — this is
