“…The hydrophobic polyvinvyl fluoride membranes were slightly more efficient in EAN, with both having similar extraction and recovery efficiencies, but a notably faster flux of 3.2 × 10 −6 m −2 s −1 in EAN as compared to 2.1 × 10 −6 m −2 s −1 in C 6 MIm PF 6 . 363 The salicylic acid dissociates in the EAN, and is extracted through ion exchange with the nitrate anions. In contrast, undissociated salicylic was extracted in C 6 MIm PF 6 .…”

“…This shows the importance of protons in the feed phase [26]. A weight of 0.09 and 0.045 g of NaCl can be considered as insufficient to allow the dissociation of the complex formed between MB and the ionic liquid at the membrane receiving phase interface and thus the not release of MB in the receiving aqueous phase [27]. And also, both k 1 and k 2 decrease with NaCl weight decrease in the feed phase.…”

In this study, an experimental study on the transport of methylene blue (MB) through bulk liquid membrane (BLM) is done and thereby best set of solvent, operating conditions, and mode of transport that would yield optimum performance of the BLM are identified. Therefore, a kinetic study of MB transport from an aqueous donor phase into an aqueous acceptor phase through a BLM containing calix[8]arene octacarboxylic acid (COCA) derivative as a carrier was studied. The influence of type of solvent, stirring speed, effect of NaCl weight in feed phase and temperature were investigated. The kinetic parameters (k 1 , k 2 , R max m , t max , J max d , J max a ) were calculated for the interface reactions assuming two consecutive, irreversible first-order reactions. In this study, the experiments demonstrated that COCA derivative is a good carrier for MB transport through liquid membranes.

“…Also, Ishizu et al [16] used a SLM containing di-n-octylamine as carrier diluted in toluene or mesitylene as organic phase to achieve the extraction of "compactin" active ingredient from a diluted aqueous solution. Kouki et al [17] studied the feasibility of the extraction of salicylic acid from acidic aqueous solution using a SLM containing aliquat-336 ionic liquid as carrier diluted in 2-octanol as organic phase.…”

Transport of lysine acetylsalicylate (LAS) through supported liquid membrane was investigated using methyl cholate (MC) as extractive agent. Kinetic and thermodynamic models were developed, based on the interaction of the substrate LAS with the extractive agent T, and the diffusion of the formed entity (TS) through the membrane. The experimental results verify the models and enable the determination of macroscopic parameters (permeabilities (P) and initial fluxes (J 0 )), as well as microscopic parameters (association constants (K ass ), and apparent diffusion coefficients (D*)), relating to formed entity (TS) and its diffusion through the membrane organic phase. Parameters such as initial concentration of the substrate in the feed phase, pH of the feed and stripping phases and temperature of the extraction medium were studied. The results obtain indicate that the mechanism of the migration of LAS through the membrane organic phase cannot be a pure diffusion movement but it takes place by successive jumps from one site to another of the extractive agent, via interaction reactions with LAS.
