Selective and Facilitated Transport of Vanadium (VO2 +) Ion through Supported Liquid Membrane and Effects of Membrane Characteristics
نویسنده
چکیده
A new supported liquid membrane (SLM) system for the selective transport of VO2 ions was prepared in this present work. The SLM was a thin porous polyvinylidene difluoride (PVDF) membrane soaked with Di-(2-ethylhexyl) phosphoric acid (D2EHPA) as mobile carrier in Xylene as organic solvent. D2EHPA acts as a highly selective carrier for the uphill transport of VO2 ions through the SLM. The transport of VO2 ions reached to 64%. In the presence of P2O7 ion as suitable masking agent in the feed solution, the interfering effects of other cations were eliminated. Keywords—Facilitated ion transport, Membrane characteristics, Supported liquid membranes, Vanadium.

The carrier facilitated transport of lithium picrate was studied using a series of non-cyclic polyethers containing different end groups and chain lengths through Bulk Liquid Membrane (BLM) and Supported Liquid Membrane (SLM) systems. The various membrane supports used are viz. PTFE, cellulose nitrate, and dialysis membrane and onion membrane. The amount of Li+ transported depends upon the stru...

Effect of Complexation Reaction Constant on the Separation of Propylene/Propane by Supported Liquid Membrane
Traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired. Facilitated transport membranes are new tools for this separation to be substituted in large scale separation of olefin-paraffin mixtures. To design a membrane process for olefin-paraffin separation, equilibriu...
