ABSTRACT:
An analytical composition, electrode and method are useful for the detection of lithium ions in an aqueous liquid. The lithium ion-selective composition comprises a lipophilic group-substituted 1,10-phenanthroline, a compound capable of solvating the phenanthroline, and a supporting matrix. This composition can be used in a lithium ion-selective electrode as a lithium ion-selective membrane. The electrode can also comprise an internal reference electrode.
