“…), and (iii) purification using crystallization or precipitation by modification of pH. The conventional processes used in the purification of amino acids require techniques as crystallization, adsorption, ionic exchanged resins, or organic solvent extraction, this last one being the most used. − This last stage of purification is a complex process whose cost can reach up to 50% of the total cost of amino acids.…”

In this work, the partitioning of four N-(2,4dinitrophenyl)-amino acids (DNP-L-leucine, DNP-L-valine, DNP-L-alanine, and DNP-glycine) in aqueous two-phase systems (ATPS) containing a new biodegradable ionic liquid cholinium alaninate, [Ch][Ala], and the inorganic salts K 3 PO 4 and K 2 HPO 4 was determined at T = 298.15 K and p = 101.3 kPa. The influence of the salt on the partition coefficients was discussed. The distribution coefficients (K) of the four studied DNP-amino acids are higher in the ATPS containing the inorganic salt K 3 PO 4 . Moreover, the experimental LLE data obtained for both ATPS {[Ch][Ala] (1) + K 3 PO 4 or K 2 HPO 4 (2) + water (3)} (previously reported) were represented using the nonrandom two-liquid thermodynamic model. Finally, a comparison of the distribution coefficients presented in this work and those found in literature for the four studied DNP-amino acids on different ATPS was performed.

“…With respect to the extraction of carboxylic acids, Grzenia et al used HFMC to remove acetic acid from biomass hydrolysates using amines as an extractant. Lin et al conducted a kinetic study of the extraction and stripping of aspartic acid from an aqueous feed using two HFMC modules. In another study, Basu and Sirkar constructed two sets of identical hollow fibers which were combined along their lengths and separated at the ends.…”

A commercially available hydrophobic polypropylene based hollow fiber membrane contactor (HFMC: Liquicel® module) was used for the removal of dissolved benzoic acid (BA) from water. The module was operated in liquid–liquid extraction (LLE) mode using BA‐laden water as feed on the lumen side and trioctylamine (TOA) diluted in 1‐octanol as extractant on the shell side of the module. The aqueous and organic streams flowed counter‐currently within the HFMC module. Experiments were carried out under different operating conditions, that is, feed flow rates, extractant flow rates, and initial BA concentrations in the feed. The synthetic wastewater was prepared using BA at concentrations ranging from 150 to 2700 ppm in water, whereas the extractant solution consisted of 0.12 M TOA in 1‐octanol. BA reacted with TOA at the interface of the aqueous and membrane phases, forming a complex that was removed by the organic extractant flowing on the shell side of the module. In this study, up to 95% removal efficiency was obtained using the HFMC operated in the LLE mode. A mathematical model was developed that simulated transport of the bulk aqueous phase and within the pores of the membrane. The model simulation results were found to be in reasonable agreement with the experimental data.
