Neutral Ionophore for Liquid Membrane Electrodes of High Selectivity for Sodium Over Potassium Ions. The preparation of a neutral ion carrier suitable as a component for liquid membrane electrodes is described. These sensors may be used for the potentiometric determination of sodium ion activities with a discrimination of potassium ions by a factor of up to 250.
