Conclusion. The liquid-liquid extraction can be identified as an important technique towards the segmentation of unmixable liquids. This particular process has a diverse set of applications in the arena of scientific and commercial production.

2.4 Liquid–liquid extraction. Liquid–liquid extraction (LLE) is based on the principle that a solute or an analyte can distribute itself in a certain ratio between two immiscible solvents, usually water (aqueous phase) and organic solvent (organic phase).

Summary. Liquid-liquid extraction (LLE), also known as solvent extraction, is a typical ternary system in the chemical engineering field, which separates chemicals from one solution to another based on the different solubility of the solute chemical in two solvents.

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 soluble in the aqueous phase.

Solid-liquid extraction processes, both traditional ones (maceration and percolation) and those introduced more recently (e.g., supercritical fluid extraction (SFE) and accelerated solvent extraction (ASE), are based on two fundamental principles: diffusion and/or osmosis.

While in a Liquid-Solid extraction water is the most common solvent used, in Liquid-Liquid extraction Diethyl Ether is most commonly used.

Liquid-liquid extraction (LLE) has been a method of sample preparation for many years[1]–[4]. It commonly involves the direct extraction of the biological or non-biological material with a water-immiscible solvent. The isolation of the analyte is achieved by partitioning it between the organic and aqueous phases.
