高温高压水热体系在科学实验、工业过程和自然界中广泛存在。为得到诸如海底热液、火山口等高温高压环境的准确信息,原位测量技术成为近年来国内外致力发展的调查研究技术,而化学传感器则是原位测量装置的重要组成部分。YSZ和Zr/ZrO2这类集成式化学传感器可以探测海底热液的pH值、H2逸度、H2S逸度。对目前国际上研究较多的YSZ,Zr/ZrO2和Ir/IrOx等高温高压化学传感器从设计原理到实际应用进行了详细的介绍,并对其发展趋势进行了展望。
The aqueous solutions at elevated-temperatures and pressures exist in scientific experiments,industrial production and the nature world.In order to get accurate information such as hydrothermal reaction,much effort has been devoted to the development of in-situ measurement techniques in recent years,and chemical sensors are important parts of the measuring devices.These sensors can detect the pH value of sea-floor hydrothermal,H2 fugacity and H2S fugacity.The design principles and practical applications of YSZ,Zr / ZrO2 and Ir / IrOx chemical sensor are described.Developmental prospects of the high temperature and high pressure chemical sensors in the future are also discussed.
