SELECTIVITY STUDIES ON LIQUID MEMBRANE, ION-SELECTIVE ELECTRODES

A series of anion-selective electrodes of the liquid membrane type has been rigorously examined with respect to selectivity characteristics using three different experimental methods. This evaluation gives, for the first time, an understanding of how selectivity ratios depend on concentration levels and other variables and yields a recommended procedure for the consistent numerical determination of selectivity ratios. The resulting selectivity data are examined in terms of a theory of liquid membrane electrodes. © 1969, American Chemical Society. All rights reserved.
