Solvent extraction is a treatment technology that uses a solvent ( a fluid that can dissolve another substance) to separate or remove hazardous organic contaminants from sludges, sediments or soil. Solvent extraction does not destroy contaminants.
Accelerated solvent extraction (ASE) of paclitaxel and related compounds from Taxus cuspidata (Japanese yew) bark has been investigated under various conditions. In ASE, pressure is applied to the sample extraction cell to maintain the heated solvent in a liquid state during the extraction.

Solvent extraction is a common form of chemical extraction using organic solvent. It is commonly used in combination with other technologies, such as solidification/stabilization, incineration, or soil washing, depending upon site-specific conditions.
Solvent extraction systems have been shown to be effective in treating sediments, sludges, and soils containing primarily organic contaminants such as polychlorinated biphenyl, polynuclear aromatic hydrocarbons, VOCs, halogenated solvents, pesticides, and petroleum-refining oily wastes.

Solvent Extraction Equipment. In principle any system which achieves mixing and separation of phases, can be used for solvent extraction in hydrometallurgy. As a practical matter, however, the extractive metallurgy industry has …
Solvent extraction, which is also called a liquid-liquid extraction, is a separation process in which two immiscible solvents are combined so that a compound or solute in one of the solvents can be isolated.
Why solvent extraction? One early means of separation was physical pressure to ‘squeeze the oil out’. The most energy efficient, practical embodiment of that method is the modern screw press.
Extract Organic phase after extraction (loaded solvent), or aqueous phase after stripping (loaded strip liquor); the solution into which transfer of a metal solute is effected; used as a verb to describe transfer of a metal solute between two immiscible liquids.
Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, ... Note that D is related to the ΔG of the extraction process.
In this case, the organic substance is on top, because the density of the organic solvent MTBE (0,74 g·cm −3) is lower than that of the other phase (about 1,00 g·cm −3). Solvent extraction, also known as Liquid–liquid extraction or partitioning, is a method to separate a compound based on the solubility of its parts.
