氧化还原电位的研究及应用

氧化还原电位(Eh)是一个描述介质氧化还原性质相对程度的化学参数,根据Eh值可以直观的比较介质氧化还原性的强弱。氧化性强,Eh值较高;还原性强,Eh值较低。氧化还原电位的测定广泛应用于水处理、土壤环境监测、金属腐蚀、湿法冶金和资源勘探等领域。本文综述了氧化还原电位在常温常压环境和高温高压环境中众多领域的应用现状,并展望了高温高压水热环境中氧化还原电位原位监测的研究。

Research on and Application of Oxidation-reduction Potential

Oxidation-reduction potential (Eh) is a chemical parameter for determining the oxidizing or reducing properties of media. Eh is reported with a numeric value, which represents oxidization when it increases and reduction when it decreases, relatively. The measurements of Eh can be applied to water treatment, soil environment monitoring, metal corrosion, hydrometallurgy, resource exploration and some other fields. In this paper, various applications of oxidation-reduction potential are summarized, including its measurements at normal temperature and pressure conditions, as well as its measurements at high temperature and high pressure conditions. In addition, the prospects of in-situ Eh measurement at high temperature and high pressure conditions are also described.
