Extraction (chemistry)

Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte moves from the initial solvent into the extracting solvent.

The term washing may also be used to refer to an extraction in which impurities are extracted from the solvent containing the desired compound.
