Journal of Membrane Science | 1984

Separation of metals by liquid surfactant membranes containing crown ether carboxylic acids

Richard A. Bartsch; Witold A. Charewicz; Sang Ihn Kang

Abstract A water-in-oil-in-water emulsion liquid membrane system is used to transport alkali metal and alkaline earth cations from an external alkaline aqueous source phase through an organic membrane containing a crown ether carboxylic acid and into the internal acidic aqueous phase of the emulsion droplet. The influence of varying the crown ether carboxylic acid structure upon the selectivity and efficiency of competitive metal ion transport is examined.


Tetrahedron Letters | 1983

New lipophilic ionizable crown ethers

Bronislaw P. Czech; Sang Ihn Kang; Richard A. Bartsch

Abstract Two new ionizable crown ethers which bear lipophilic groups are synthesized and found to exhibit selectivity for complexation of K+ in competitive solvent extractions of alkali metal cations.
