A Review of the Potentiometric Samarium Ion-Selective Sensors

Abstract

The key role of developing new and effective analytical tools and techniques for various species need not be discussed. Furthermore, reviewing the trends dominating the development of such tools and techniques can be of great importance to those active in the research and development areas. In designing an electrochemical sensor, finding a suitable selectophore is very important. In potentiometric ion-selective sensors, ionophores play a significant role in the selective response of the sensor. Besides the ionophore, other components of the electrode can improve the response. This review article tends to focus on the development of samarium ion electrodes over the past decades to provide researchers in the area of selective electrochemical analysis with a better insight into one of the various areas of electrochemical sensor development. Accordingly, the history of the development of potentiometric ion-selective sensors for samarium ions, with details on the ionophores, compositions, and electrochemical properties thereof has been provided.
