Liquid-liquid extraction

Journal of Chemical Education, 1967
Describes how liquid-liquid extraction can be done using commercially available substances and an apparatus of small dimensions that still allows an experiment to be followed visually.

Molecular Forces in Liquid–Liquid Extraction

Langmuir, 2021
The phase transfer of ions is driven by gradients of chemical potentials rather than concentrations alone (i.e., by both the molecular forces and entropy). Extraction is a combination of high-energy interactions that correspond to short-range forces in the first solvation shell such as ion pairing or complexation forces, with supramolecular and ...

LIQUID‐LIQUID EXTRACTION IN PEPTIDE SYNTHESIS

International Journal of Peptide and Protein Research, 1980
An efficient procedure of peptide synthesis in solution based on liquid‐liquid extraction for the purification of intermediates (two‐phase method) is described. Generally, peptide segments of 10 and in favorable cases 15 amino acids can be prepared by using conventional blocking groups.

Influence of Electrolytes on Liquid−Liquid Extraction

Industrial & Engineering Chemistry Research, 1998
The strong influence of electrolytes on the partition behavior of charged species is demonstrated in aqueous and aqueous−organic two-phase systems used for extraction. The effects are modeled with an extended Albertsson model which takes into account the electrostatic potential difference between coexisting phases.

Phosphorus Recovery by Liquid–Liquid Extraction

Separation Science and Technology, 2009
It is acknowledged that phosphorus removal is more crucial in comparison with nitrogen removal for preventing algae glooming and eutrophication. Chemical and biological methods are common methods for the P removal. Excessive sludge production and difficulties of recovering phosphorus are concerns in terms of sustainable waste management.

Electrochemically Modulated Liquid−Liquid Extraction of Ions

Analytical Chemistry, 2005
The development of ion extraction methods under electrochemical control via electrochemistry at the interface between two immiscible electrolyte solutions is discussed. A hydrodynamic flow injection system was used for the potentiostatic extraction of non-redox-active species from a flowing aqueous phase into a stationary organogel phase.

Purification of Enzymes by Liquid-Liquid Extraction

1982
The article reviews the current status of the application of aqueous two-phase systems for the extractive purification of enzymes, especially with regard to large-scale processing. The method can be used for the separation of proteins from cell debris as well as for further purification. The latter can be performed by a series of single step partitions,
