Extraction (chemistry)

Extraction in chemistry is a separation process consisting in the separation of a substance from a matrix. It includes Liquid liquid extraction, and Solid phase extraction. The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte move from the water into an organic layer.
