Solvent Extraction II Solvent extraction is a method to separate mixtures of organic acids, bases, and neutral compounds by use of an organic solvent. It is used to treat soils with organic contaminants such as halogenated solvents and petroleum wastes and is generally used with other technologies such as solidification/stabilization, incineration, or soil washing.
