Facilitated Transport of Alkali Metal Cations Through Supported Liquid Membranes with Fatty Acids... [Pg.75]

Neutral macrocyclic ethers have been used to facilitate the transport of cations across liquid membranes. It has been found that the anion desolvation energy barrier is one of the more important factors in controlling the rate of transfer across the membrane. a-Carboxy-a>-hydroxypolyethers containing ethylene and 1,2-phenylene units can transport metal-ions from aqueous alkali metal hydroxide to an aqueous solution of hydrochloric add through a liquid membrane of hexan-l-ol. However, unlike natural carboxylic ionophores, active transport against the alkali metal-ion concentration gradient could not be observed. ... [Pg.403]
