Extraction Equilibria of Acrylic Acid from Aqueous Solutions by Amberlite LA-2 in Various Diluents

Journal of Chemical & Engineering Data, 2010
Amberlite LA-2 (a secondary amine mixture) has been studied for its ability to extract acrylic acid at different amine concentrations. The extraction of acrylic acid by Amberlite LA-2 dissolved in seven single solvents (cyclohexane, 2-octanone, toluene, methyl isobutyl ketone (MIBK), iso-octane, hexane, and 1-octanol) has been investigated with respect

Selective Extraction of Cadmium from Multicomponent Acidic Leach Solutions by Emulsion Liquid Membrane using Amberlite LA-2 as Extractant

Separation Science and Technology, 2013
The zinc plant purification cake (CINKUR Co., Turkey) was leached with hydrochloric acid. The extraction and concentration of cadmium from this acidic leach solution by an emulsion liquid membrane (ELM) using secondary amine (Amberlite LA-2) as extractant has been studied. The effect of the fundamental parameters influencing the extraction process, for

Immobilization of fungal (Trametes versicolor) laccase onto Amberlite IR-120 H beads: Optimization and characterization

Process Biochemistry, 2013
Laccase from Trametes versicolor was immobilized on Amberlite IR-120 H beads. Maximum immobilization obtained was 78.7% at pH = 4.5 and temperature T = 45 degrees C. Kinetic parameters, K-m and V-max values, were determined respectively as 0.051 mM and 2.

Reaction Equilibrium of Penicillin G with Amberlite LA‐2 in a Nonpolar Organic Solvent

Biotechnology Progress, 2002
Abstract Studies have been made of the reactive extraction of penicillin G by Amberlite LA‐2, a secondary amine, dissolved in kerosene. On the basis of the previous works about extraction equilibria of monocarboxylic acids by some secondary amines in low polar organic solvents, four equilibrium models were suggested to describe the ...

Comparative Study on Reactive Extraction of Nicotinic Acid with Amberlite LA‐2 and D2EHPA

Separation Science and Technology, 2007
Abstract The comparative study of reactive extraction of nicotinic acid with Amberlite LA‐2 and D2EHPA in three solvents with different polarity indicated that the extractant type and solvent polarity control the extraction mechanism. Thus, the reactive extraction with Amberlite LA‐2 in low‐polar solvents occurs by means of the interfacial formation of

Distribution equilibrium of penicillin G between water and organic solutions of Amberlite LA-2

The Chemical Engineering Journal and the Biochemical Engineering Journal, 1996
Abstract Equilibrium studies on the distribution of penicillin G between aqueous solutions and Amberlite LA-2 (a secondary amine) in mixtures of n -butyl acetate and kerosene were made in the temperature range 288–308 K. Experiments were performed as a function of aqueous pH, penicillin G concentration in the aqueous phase, and amine concentration ...
