  2. 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).

  3. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Thin-layer chromatography is used to separate components of a plant extract, illustrating the experiment with plant pigments which gave chromatography its name In chemical analysis , chromatography is a laboratory technique for the separation of a mixture into its components.

  4. 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.

  5. Partition chromatography - Wikipedia

    en.wikipedia.org/wiki/Partition_chromatography

    In contrast, Martin and Synge developed and described a chromatographic separation process whereby compounds were partitioned between two liquid phases similar to the separatory funnel liquid-liquid separation dynamic. This was an important departure, both in theory and inder equilibrium conditions. [4]

  6. Leaching (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Leaching_(chemistry)

    Leaching can occur naturally seen from plant substances (inorganic and organic), [2] [3] solute leaching in soil, [4] and in the decomposition of organic materials. [5] Leaching can also be applied affectedly to enhance water quality and contaminant removal, [ 1 ] [ 6 ] as well as for disposal of hazardous waste products such as fly ash , [ 7 ...

  7. Centrifugal partition chromatography - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_Partition...

    Centrifugal partition chromatography does not use any solid stationary phase, so it guarantees a cost-effective separation for the highest industrial levels. As opposed to countercurrent chromatography, it is possible to get very high flow rates (for example 10 liters / min) with active stationary phase ratio of >80%, which guarantees good ...

  8. Countercurrent distribution - Wikipedia

    en.wikipedia.org/wiki/Countercurrent_distribution

    Countercurrent distribution is a separation process that is founded on the principles of liquid–liquid extraction where a chemical compound is distributed (partitioned) between two immiscible liquid phases (oil and water for example) according to its relative solubility in the two phases.

  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.
