B. Hundhammer et al., INVESTIGATION OF ION TRANSFER ACROSS THE MEMBRANE-STABILIZED INTERFACE OF 2 IMMISCIBLE ELECTROLYTE-SOLUTIONS .3. FACILITATED ION TRANSFER, Journal of electroanalytical chemistry [1992], 371(1-2), 1994, pp. 1-11
The transfer of Na+, K+, Cs+ and Tl+ ions facilitated by DB[18]C-6 has
been studied employing a concentration pulse (flow injection) techniq
ue. The transfer of Tl+ has also been found to be facilitated by the t
etraphenylborate ion. The facilitated transfer of Na+ and K+ ions has
been used successfully in the simultaneous determination of the two io
ns in standard sera and in blood serum samples.
