    Solvent extraction, also called liquid-liquid extraction (LLE) and partitioning, is a method to separate compounds based on their relative solubilities in two different immiscible liquids.

  • What is Solvent Extraction? (with pictures)

    SummaryUseTypesPropertiesSolvent extraction is a method for separating a substance from one or more others by using a solvent. It relies on variations in the solubilities of different compounds in different substances. In most cases, the substance to be extracted, which may be a solid, a liquid or a gas, is dissolved in a liquid, along with other substances, and a liquid solvent is used for the extraction this is sometimes called liquid-liquid extraction. The technique may also be applied to solid materials that contain compounds that need to be extracted
  • What is Solvent Extraction and Why is it Important?

    Solvent extraction has always proved itself very helpful as a recovery method for many components. It is a method of separating compounds on the basis of their solubility in two different immiscible liquids like water and organic compound.
