  2. Extraction (chemistry) - Wikipedia

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

    Laboratory-scale liquid-liquid extraction. Photograph of a separatory funnel in a laboratory scale extraction of 2 immiscible liquids: liquids are a diethyl ether upper phase, and a lower aqueous phase. Soxhlet extractor. Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution ...

  3. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    The process thus in its essence is similar to distillation, however the material which is condensed on the cooler surface then has to be removed mechanically, thus requiring different laboratory equipment. Bioleaching is the extraction of metals from their ores through the use of living organisms. Separation process. From Crystallization

  4. Extraction - Wikipedia

    en.wikipedia.org/wiki/Extraction

    Extraction (chemistry), the separation of a substance from a matrix; Primary extraction, the act of removing a spent cartridge from the chamber of a firearm; Fragrance extraction, the process of obtaining fragrant oils and compounds from raw materials; Resource extraction, the process of locating, acquiring and selling any resource

  5. Perstraction - Wikipedia

    en.wikipedia.org/wiki/Perstraction

    Perstraction is the separation technique developed from liquid-liquid extraction. Due to the presence of the membrane a wider selection of extractants can be used, this can include the use of miscible solutions, for example the recovery of ammonia from waste water using sulphuric acid. [3] This process is analogous to pervaporation in some ways ...

  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. Solid-phase extraction - Wikipedia

    en.wikipedia.org/wiki/Solid-phase_extraction

    Solid-phase extraction (SPE) [1] is a solid-liquid extractive technique, by which compounds that are dissolved or suspended in a liquid mixture are separated, isolated or purified, from other compounds in this mixture, according to their physical and chemical properties. Analytical laboratories use solid phase extraction to concentrate and ...

  8. Leaching (chemistry) - Wikipedia

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

    Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent. [1] Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods.

  9. Supercritical fluid extraction - Wikipedia

    en.wikipedia.org/wiki/Supercritical_fluid_extraction

    Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent. Extraction is usually from a solid matrix, but can also be from liquids .
