A Kinetic Investigation of a Carrier-Mediated Transport through a Bulk Liquid Membrane
The kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (L) through a bulk liquid membrane is studied experimentally and theoretically. The proposed model is based on the assumption of a pure diffusion of the complex salt [K·L]+SCN¯ through the liquid membrane stagnant films at the interfaces. It illustrates the ...

متن کاملKinetics of Chromium(III) Transport Through a Liquid Membrane Containing DNNSA as a Carrier
Kinetics of Cr(III) ions transport through a bulk liquid membrane containing dinonylnaphthalenesulfonic acid (DNNSA) as a carrier, flowing over aqueous phases, has been examined. Special attention has been paid to the effect of the membrane's velocity flow on the chromium concentration decrease in a feed phase. For the description of relationships of chromium(III) concentration in particular ph...
متن کاملExtraction of organic acids using a supported liquid membrane.
Liquid membranes usually consist of an extracting agent (carrier) in an organic solvent which separates "feed" and "stripping" phases containing aqueous solutions of the solute of interest and a stripping agent, respectively. In supported liquid membranes (SLMs) the membrane solution is immobilised into a thin solid microporous support, between the feed and stripping phases where transport is f...
متن کاملSelective transport of silver ion through a supported liquid membrane using hexathia-18-crown-6 as carrier.
A facile supported liquid membrane (SLM) system for the selective and efficient transport of silver ion is introduced. The SLM used is a thin porous polyvinyldifluoride membrane impregnated with hexathia-18-crown-6 (HT18C6) dissolved in nitrophenyloctyl ether. HT18C6 acts as a specific carrier for the uphill transport of Ag+ ion as its picrate ion paired complex through the SLM. In the presence...
