Studies on the electrochemical approach to ion solvation

Abstract

Two problems are discussed concerning the electrochemical studies on ion solvation: one is the problem of electrochemical sensors for ion solvation and the other is the problem of comparing the electrode potentials in different solvents. On the former, the applications of ion-selective electrodes and pH-ISFETs are mainly considered. On the latter, the three components of the liquid junction potential (LJP) between different solvents are discussed and then a new method of estimating the LJP is presented, being compared with the conventional methods.
