Ion-Selective Electrode Reviews, Volume 3, provides a review of articles on ion-selective electrodes (ISEs). The volume begins with an article on methods based on titration procedures for surfactant analysis, which have been developed for discrete batch operation and for continuous AutoAnalyser use. Separate chapters deal with detection limits of ion-selective electrodes; the possibility of using inorganic ion-exchange materials as ion-sensors; and the effect of solvent on potentials of cells with ion-selective electrodes. Also included is a chapter on advances in calibration procedures, the development of long range sensors, and the use of ion-buffers for extending known calibration ranges—all of which are essential to obtaining and extending the linear ranges of ISEs. The final chapter presents a listing of titles covering topics such as electrode development and new electrodes; mechanistic and theoretical aspects; solution chemistry and ISEs; standard addition methods; potentiometric titrations; automatic analysis and continuous monitoring; and applications of ISEs.
