14 Where V represent solvent volume and the other quantities remain as previously defined. The percent extraction may be seen to vary with the volume ratio of the two phases as well as with D. It may also be seen from equation (2.3) that at extreme values of “D”, “E” becomes less sensitive to changes in “D”.For example, at a phase volume ratio of unity,

Liquid–liquid extraction Wikipedia

2020-06-10· 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.
