LIQUID‐LIQUID EXTRACTION IN PEPTIDE SYNTHESIS
International Journal of Peptide and Protein Research, 1980An 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, 1998The 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, 2009It 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, 2005The 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
1982The 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,
