Solvent extraction is one of the separation methods in which one component or solute present in one phase is extracted into another phase by using a suitable solvent. Thus, the process by which a solute is transformed from one phase to a new phase is known as extraction. This process of extraction using a suitable solvent is popularly known as solv...
It is one of the most important separation techniques used in environmental, clinical, and industrial laboratories. Few applications have been mentioned here. 1. Public drinking water supplies are routinely monitored for trihalomethane, which is known for carcinogenicity. These are extracted from their aqueous matrix by liquid-liquid extraction usi...

Nov 3, 2022 · Liquid-liquid extraction (abbreviated as extraction) is one of the most common basic operations in the organic chemistry laboratory and allows the isolation and purification of a product resulting from a chemical reaction. Extraction can be defined as the transfer of a substance X from a liquid phase A to another liquid phase B.
Jun 20, 2021 · Liquid-liquid extraction involves the exchange of certain com- pounds between two solvents that are immiscible or only partially miscible. Liquid-liquid extraction is also very commonly used for washing an organic phase, for example to remove inorganic compounds, or to protonate or deprotonate bases or acids, respectively, so they become ...

This section will provide an overview of the basic concept of extraction in organic chemistry, its significance and how it has been used in the scientific research and industry over the years.
Dec 30, 2013 · Standard solutions that are used for extraction are: 5 % hydrochloric acid, 5 % sodium hydroxide solution, saturated sodium bicarbonate solution (~6 %) and water. All of these solutions help to modify the (organic) compound and make it more water-soluble and therefore remove it from the organic layer. More concentrated solutions are rarely used ...
