在七十年代以前,pH电极敏感器件主要限于各种金属—氢电极、金属—金属氧化物电极及玻璃电极等。近十年来,发展了一系列新型pH敏感器件,加快离子导体、半导体敏感器件、中性载体及化学修饰pH电极等。同时,对高温高压下的pH测量技术作了若干新的研究,本文扼要介绍这方面的新进展。 Before the seventies, pH electrode sensitive devices were mainly confined to a variety of metal - hydrogen electrodes, metal - metal oxide electrodes and glass electrodes. In the past ten years, a series of new pH sensitive devices have been developed to speed up ion conductors, semiconductor sensitive devices, neutral carriers and chemically modified pH electrodes. At the same time, some new researches on pH measurement technology under high temperature and high pressure are made. This article briefly introduces the new progress in this field.
