Liquid-Liquid Extraction of Naphthenic Acid Using Thiocyanate Based Ionic Liquids

Biocompatible Ionic Liquids in Liquid – Liquid Extraction of Lactic Acid: A Comparative Study

Ionic liquids consisting of a phosphonium cationic moiety and a saccharinate anion are synthesized and compared with their precursors, phosphonium chlorides, in reference to their extraction efficiency towards L-lactic acid. On the base of measurements of the acid and the water partitioning in the equilibrium biphasic systems, the molar ratios between acid, water and ionic liquid are estimated ...

Selective Liquid-Liquid Extraction of Lead Ions Using Newly Synthesized Extractant 2-(Dibutylcarbamoyl)benzoic Acid

A new carboxylic acid extractant, named 2-(dibutylcarbamoyl)benzoic acid, is prepared and its potential for selective solvent extraction and recovery of lead ions from industrial samples was investigated. The slope analysis indicated that the lead ions are extracted by formation of 1:2 metal to ligand complexes. The effect of the parameters influencing the extraction efficiency including kind o...

Amino-acid recovery using ionic liquids: Partitioning in water + ionic liquid systems

The partition of a series of dinitrophenylated amino-acids is studied experimentally in two (Ionic Liquid + Sodium Phosphate Buffer) biphasic systems at 23 oC. The ionic liquids used in these experiments are 1-hexyl-3-methylimidazolium tetrafluoroborate, [C6mim][BF4], and 1-decyl-3-methylimidazolium tetrafluoroborate, [C10mim][BF4]. pH of the initial aqueous solution is fixed at 7.4 using a sui...

Liquid-liquid extraction of lysozyme using a dye-modified ionic liquid.

An affinity-dye, Cibacron Blue 3GA (CB), derivatized organic salt [BMIM]3[CB] was synthesized for lysozyme extraction. This compound was formed by mixing an ionic liquid (IL) [BMIM][Cl] and the silver salt of CB. Liquid-liquid extractions of lysozyme from the aqueous and [BMIM]3[CB] in [BMIM][PF6] solutions were examined in this study. The transfer of lysozyme from the aqueous phase to the IL p...
