Intensified liquid-liquid extraction of biomolecules using ionic liquids in small channels
نویسندگان
چکیده
The continuous extraction of an amino acid from aqueous solution into ionic liquid phase was studied experimentally in small channels, demonstrating a double intensification the solvent used and overall process. Channels with 0.5, 1 2 mm internal diameter were for acid, L-tryptophan (0.005 mol L?1), hydrophobic liquid, 1-Butyl-3-methylimidazolium Bis (trifluoromethanesulfonyl)imide, [C4mim][Tf2N] presence crown ether extractant , Dicyclohexano-18-crown-6, (DC18C6). A mechanism proposed which involved ammonium centre forming hydrogen bonds 18-crown-6 part at 1:1 ratio. Partition coefficients up to 25 obtained. experiments carried out during plug flow where interfacial areas reported reached 5500 m2m?3 50% volume fractions. Extraction efficiencies 90% obtained residence times less than 30 s. Overall mass transfer (KL?) found 0.14 s?1.

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 ...
متن کاملEvaluation of Response Surface Methodology in Dispersive Liquid-Liquid Microextraction for Lead Determination Using Ionic Liquids
This paper describes a dispersive liquid–liquid microextraction (DLLME) procedure using room temperature ionic liquids (RTILs) coupled with flame atomic absorption spectrometry detection with microsample introduction system capable of quantifying trace amounts of lead. In the proposed approach, ammonium pyrrolidine dithiocarbamate (APDC) was used as a chelating agent and 1-hexyl-3-methylimmidaz...
متن کاملLiquid-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...
متن کاملSurface tension of ionic liquids and ionic liquid solutions.
Some of the most active scientific research fronts of the past decade are centered on ionic liquids. These fluids present characteristic surface behavior and distinctive trends of their surface tension versus temperature. One way to explore and understand their unique nature is to study their surface properties. This critical review analyses most of the surface tension data reported between 200...
