离子选择性电极是电化学传感器中重要的研究方向之一.随着科学的进步和发展,传统液接式离子选择性电极显示出越来越多的弊端,因此,人们尝试研制全固态的离子选择性电极.经过了数10年的研究,其已经初步应用到临床化验、环境监测以及工业分析等领域.本文根据固态转接层材料的离子-电子转移原理的不同,将全固态离子选择性电极分为:双电层电容型全固态离子选择性电极、赝电容型全固态离子选择性电极以及双电层电容和赝电容混合型的全固态离子选择性电极,并综述了上述3种不同类型的全固态离子选择性电极的研究进展,阐述了对应的响应机理,并展望了其未来的发展趋势.
Ion selective electrode is one of the important research directions in electrochemical sensor.With the progress and development of science, the traditional liquid junction ion selective electrode shows more and more disadvantages, therefore, people try to develop all-solid-state ions Selective electrode.After 10 years of research, it has been initially applied to clinical laboratory, environmental monitoring and industrial analysis fields.In this paper, based on the solid-state transition layer material ion-electron transfer principle, the all-solid ion selectivity The electrodes are divided into two types: an all-solid-state ion selective electrode with an electric double layer capacitance type, a pseudocapacitive all solid state ion selective electrode, an all-solid ion selective electrode with an electric double layer capacitor and a pseudocapacitance hybrid type, Type of all-solid-state ion selective electrode research progress, expounded the corresponding response mechanism, and prospects of its future trends.
