Abstract
In order to trace the changes in the activity of ions in dipolar aprotic solvents, poly(acrylamide) membrane based ion selective electrodes were developed in the author's laboratory. This review covers (1) the development of the electrodes, including the synthesis of host compound modified poly(acrylamide); (2) potentiometric response properties of the electrodes; (3) investigations of the response mechanism by means of spectrophotometric and cyclic voltammetric methods; and (4) applications to determine the solubility products of slightly soluble electrolytes in dipolar aprotic solvents, successive complex formation constants of ions with some dipolar aprotic solvent molecules, and standard molar Gibbs energies of ions transfer.
