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 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 کاملIon transport through diffusion layer controlled by charge mosaic membrane
The kinetic transport behaviors in near interface of the membranes were studied using commercial anion and cation exchange membrane and charge mosaic membrane. From chronopotentiometry above the limiting current density, the transition time was estimated. The thickness of boundary layer was derived with conjunction with the conventional limiting current density and the transition time from stea...

متن کاملStudies on Transport of Carbonate Ions through a Supported Liquid Membrane
The transport of carbonate ions through a supported liquid membrane in the presence and absence of carriers has been explored. The liquid membrane used was the combined liquid cation and anion exchangers in toluene immobilized in the porous polypropylene support. The permeability coefficient (P) of carbonate ions transport from the source to receiving through membrane phase has been estimated. ...
