“…Techniques based on bulk liquid membranes (BLM), emulsion liquid membranes (ELM), and supported liquid membranes (SLM) have been widely used to separate organic compounds and metal ions from aqueous solutions [21][22][23][24] . BLM-based separation technique is the most simple and efficient among them 20 . BLM have been extensively used in the separation of carboxylic acids, e.g., formic, acetic, propionic, butyric, levulinic [11][12][13] .…”

“…Various techniques for the separation of carboxylic acids from aqueous solutions, including liquid-liquid extraction, adsorption, nanofiltration, ultrafiltration, ion exchange, electrodialysis, reverse osmosis, distillation, liquid membrane separation (LMS), have been intensively studied [10][11][12][13][14][15][16] . LMS has a series of advantages, e.g., fast and selective separation of target compounds, high transport efficiency, use in case of diluted solutions, low cost compared to other methods of separation, simple handling, easy to scale up [10][11][12][13][17][18][19][20] .…”

“…Mathematical modelling is an effective tool used to predict the performances of liquid membrane-based separation 11,[17][18][19][20]28,30,31 . Process performances depends on different factors, e.g., type and initial concentration of separating species in the feed phase, type of organic solvent in the membrane phase, type and concentration of carrier in the membrane phase, type and concentration of stripping agent in the stripping phase, type of separation equipment, stirring speed, temperature, pH of feed and stripping phases, volumes of feed, membrane, and stripping phases and their contact surface areas.…”

The paper has aimed at studying the transfer of indole 3-acetic acid (IAA) from a feed aqueous solution to a stripping aqueous solution of NaOH using a chloroform bulk liquid membrane and trioctylamine (TOA) as a ligand (L). Initial molar concentrations of IAA in the feed phase, cIAA,F0 (10-4-10-3 kmol/m3), of TOA in the membrane phase, cL,M0 (10-2 and 10-1 kmol/m3), and of NaOH in the stripping phase, cNaOH,S0 (10-2 and 1 kmol/m3), were selected as process factors. Their effects on the final values of IAA concentration in the feed phase (cIAA,Ff) and stripping solution (cIAA,Sf), extraction efficiency (EF), distribution coefficient (KD), and recovery efficiency (ER) were quantified using multiple regression equations. Regression coefficients were determined from experimental data, i.e., cIAA,Ff,ex=0.02-1×10-4 kmol/m3, cIAA,Sf,ex=0.22-2.58×10-3 kmol/m3, EF,ex=90.0-97.9%, KD,ex=9.0-46.6, and ER,ex=66.5-94.2%. It was found that cIAA,F0 had the most significant positive effect on cIAA,Ff and cIAA,Sf, whereas cNaOH,S0 had a major positive effect on EF, KD, and ER. A deterministic model based on mass transfer of IAA was developed and its parameters, i.e., mass transfer coefficient of IAA-L complex in the liquid membrane (0.08-1.15×10-6 m/s) and extraction constant (1033.9-1779.7 m3/kmol), were regressed from experimental data. The effect of cL,M0 on both parameters was significant.

Chemical purifications are critical processes across many industries, requiring 10 - 15% of humanity’s global energy budget1,2. Coordination cages are able to catch and release guest molecules based upon their size and shape3,4, providing a new technological basis for achieving chemical separation. Here we show that aqueous solutions of FeII4L6 and CoII4L4 cages can be used as liquid membranes. Selective transport of complex hydrocarbons across these membranes enabled the separation of target compounds from mixtures under ambient conditions. The kinetics of cage-mediated cargo transport are governed by guest binding affinity. Using sequential transport across two consecutive membranes, target compounds were isolated from a mixture in a size-selective fashion. The selectivities of both cages thus enabled a two-stage separation process to isolate a single compound from a mixture of physicochemically similar molecules.
