  2. Decantation - Wikipedia

    en.wikipedia.org/wiki/Decantation

    Decanting a liquid from a solid. Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. [1] The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving denser liquid or the solid behind.

  3. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.

  4. Separatory funnel - Wikipedia

    en.wikipedia.org/wiki/Separatory_funnel

    A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities. [1]

  5. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Pervaporation is a method for the separation of mixtures of liquids by partial vaporization through a non-porous membrane. Extractive distillation is defined as distillation in the presence of a miscible, high boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture.

  6. Liquid–liquid extraction - Wikipedia

    en.wikipedia.org/wiki/Liquid–liquid_extraction

    A separatory funnel used for liquid–liquid extraction, as evident by the two immiscible liquids.. Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar).

  7. Centrifugation - Wikipedia

    en.wikipedia.org/wiki/Centrifugation

    Density gradient centrifugation is known to be one of the most efficient methods for separating suspended particles, and is used both as a separation technique and as a method for measuring the density of particles or molecules in a mixture. [17] It is used to separate particles on the basis of size, shape, and density by using a medium of ...

  8. Fractionating column - Wikipedia

    en.wikipedia.org/wiki/Fractionating_column

    A fractionating column or fractional column is equipment used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on their differences in volatility. Fractionating columns are used in small-scale laboratory distillations as well as large-scale industrial distillations.

  9. Column chromatography - Wikipedia

    en.wikipedia.org/wiki/Column_chromatography

    Column chromatography in chemistry is a chromatography method used to isolate a single chemical compound from a mixture. Chromatography is able to separate substances based on differential absorption of compounds to the adsorbent; compounds move through the column at different rates, allowing them to be separated into fractions.
