π Electron induced separation of organic compounds using supported ionic liquid membranes

Separating a multicomponent and multiphase liquid mixture with a 3D-printed membrane device

“…, only ∼2.7% of the initial benzene is separated after 24 hours. The benzene throughput , from the feed to the receiving solution through SILMs can be described by eqn (2) shown below : 25 Here A is the surface area of the membrane that is in contact with the solution, k is mass transfer coefficient of the solute, C f and C r are concentrations of benzene in the feed solution and in the receiving solution, respectively, V is the volume of the receiving solution, t is time. To increase the separation throughput of SILMs, surface area to volume (A/V) ratio needs to be maximized.…”

Utilization of ionic liquids for preferential separation of thorium during the determination of trace metallic constituents in thorium matrix using ICP-OES

“…34–37 By grafting poly(ionic liquid) brushes on the membrane surface, ionic liquid-based membranes have recently been employed for electric field sensing, unconventional pi–pi interaction-based separation and improvement in antimicrobial characteristics. 38–42 In nuclear industries, so far ionic liquids have been used in the back end of the nuclear fuel cycle either in aqueous or in non-aqueous reprocessing. In non-aqueous reprocessing, ionic liquids have been used for spent fuel dissolution directly into them, and subsequent electro-deposition of required metal ions from them to avoid the criticality issue.…”

Separating Miscible Liquid–Liquid Mixtures Using Supported Ionic Liquid Membranes

“…In 2021, Chen et al have studied three imidazolium-based ILs ([HMIM]­[OTF], [OMIM]­[OTF], and [BMIM]­[OTF]) by molecular dynamics simulation for n -heptane-t-butanol separation application, and they concluded that [HMIM]­[OTF] is the best candidate for the desired separation. Kamaz et al studied three different imidazolium-based SILMs in separating benzene, naphthalene, and phenanthrene in tetradecane solution. Based on the experimental results, Kamaz et al concluded that benzene has the highest flux in all three ILs used, followed by naphthalene and phenanthrene.…”

“…Kamaz et al studied three different imidazolium-based SILMs in separating benzene, naphthalene, and phenanthrene in tetradecane solution. Based on the experimental results, Kamaz et al concluded that benzene has the highest flux in all three ILs used, followed by naphthalene and phenanthrene. They also reported that the hydrophilic ILs were stable in SILMs after immersion in water, hexane, and tetradecane for up to 165 h.…”
