高温高压水溶液用Ag/AgCl参比电极研究现状及发展趋势

STATE OF THE ART AND FUTURE TRENDS OF Ag/AgCl REFERENCE ELECTRODES FOR HIGH TEMPERATURE AND HIGH PRESSURE AQUEOUS SYSTEMS

对目前国内外高温高压水溶液用Ag/AgCl参比电极的研究现状进行了回顾和总结 ,主要针对内置式参比电极和外置式参比电极的结构和存在的问题进行了讨论 .两种电极在结构上的发展都是从复杂到简单实用 ,大量新材料和新技术的应用使参比电极的性能有了很大的提高 .相比来说 ,内置式参比电极由于结构简单 ,电位稳定 ,比较适合用于热力学方面的研究 ;而外置式参比电极的结构比较复杂 ,适合于动力学方面的研究 .并对参比电极的发展趋势进行了展望 .

The developments of the Ag/AgCl reference electrodes for high temperature and high pressure aqueous systems are reviewed.Particular attention is paid to the designs and the problems of the internal and external reference electrodes.The development in structure is from complexity to simpleness.The qualities of the electrodes are improved mostly because of the use of lots of new materials and technologies.In contrast,internal reference electrodes are adapt to be used in thermodynamics because of simple structures and stable potentials,external reference electrodes in kinetics because of the complex structure.A forecast is given for their future trends.
