    Extraction (chemistry) - Wikipedia

    Extraction in chemistry is a separation process consisting in 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. This is based on exactly how the analyte moves from the initial solvent into the extracting solvent.
