A study of phenol transport was conducted in correlation to the evaluation of copoly (eugenol-divinylbenzene, DVB) as carrier using polymer inclusion membrane (PIM) method. The performance of copoly (eugenol-DVB) ABSTRAK Telah dilakukan penelitian tentang transpor fenol yang berkaitan dengan evaluasi kopoly(eugenoldivinilbenzena, DVB) sebagai senyawa pembawa (carrier) menggunakan metode polymer inclusion membrane (PIM). Pada tulisan ini kopoly(eugenol-DVB) 12% diobservasi berdasarkan pada parameter membrane liquid (ML) loss. Beberapa variasi, termasuk pengaruh konsentrasi plasticizer, kecepatan pengadukan, dan pengukuran waktu hidup (lifetime) membran telah diteliti. Berkaitan dengan waktu hidup, juga telah dipelajari pengaruh konsentrasi garam NaNO 3 . Tensile strength (kuat tarik) membran sebelum dan sesudah transpor diukur dan dikarakterisasi menggunakan SEM (Scanning Electron Microscope

Membrane Separation Polymer Ionic liquidIntegrated system a b s t r a c t Many types of membranes are available to enrich hydrogen. Nevertheless, there are some with special potential for biohydrogen purification such as the non-porous, polymeric and ionic liquid based membranes. The attractiveness of these membranes comes from the fact that they can be employed nearly under the conditions where biohydrogen formation taking place. Therefore, they appear as promising candidates to be coupled with hydrogen producing bioreactors and hence giving the chance for in situ biohydrogen concentration.It is known that the feasibility and efficiency of membrane technology e beside material selection and module design e significantly depend on the separation circumstances.Thus, the operation of membranes is a key issue and the most important factors to be considered for gas purification are the composition of gas to be separated, the pressure and temperature applied. The scope of this study is to give a comprehensive overview on the recent applications of non-porous, polymeric and ionic liquid supported membranes for biohydrogen recovery, placing emphasis on the operational conditions affecting membrane's behavior and performance. Furthermore, a novel concept for integrated biohydrogen production and purification using gas separation membranes is demonstrated and discussed.

“…SILMs not only guarantee minimal membrane liquid loss through solvent evaporation, but also allow more stable membranes due to the higher viscosity of ILs and greater capillary forces between the desired ionic liquid and the support membrane. 11,12 There has been a growing interest in the use of ILs in supported liquid membranes, particularly for CO 2 separation, not only due to the high levels of solubility and selectivity of CO 2 in these fluids relative to the other gases, namely CH 4 and N 2 , [13][14][15][16] but also because of the ability to tailor many of their physical and chemical properties by combining different cations and anions or by adding functional groups. 17,18 Consequently, several studies on the permeation properties of gases through SILM systems have explored the effect of the IL structure.…”

In order to increase flexibility in tailoring the permeability and selectivity of supported ionic liquid membranes (SILMs) for flue gas separation and natural gas purification, this work explores the use of ionic liquid mixtures. For that purpose, gas permeation properties of CO 2 , CH 4 were measured at 293 K using a time lag apparatus. In addition to gas permeation results, the thermophysical properties of those mixtures, namely viscosity and density, were also determined so that trends between the two types of properties could be evaluated. The results show that mixing [Ac] or
