Transport of copper(II) through supported liquid membrane containing LIX65N.

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 ...

Selective Transport of Propylene by Silver Ion Complex Through an Immobilized Liquid Membrane

Transport of Metal Ions through Cellulose Fiber Supported Solid Membrane into Tributyl Phosphate Containing Mixed Solvents

A novel cation exchange fiber supported solid membrane was developed for transport of cobalt, manganese and nickel metal ions. Fiber supported solid membrane was prepared by chemically modifying the cellulose fibers with citric acid. In the fiber supported solid membrane, the diffusion by capillary action by keeping the liquid phase in the porous solid fiber and ion exchange mechanism were used...

Studies 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. ...

Transport of alkali halides through a liquid organic membrane containing a ditopic salt-binding receptor.

A ditopic receptor is shown to have an impressive ability to recognize and extract the ion pairs of various alkali halides into organic solution. X-ray diffraction analysis indicates that the salts are bound in the solid state as contact ion pairs. Transport experiments, using a supported liquid membrane and high salt concentration in the source phase, show that the ditopic receptor can transpo...
