摘要
阐述了电位-pH图的意义及应用,比较了绘制理论电位-pH图和实验电位-pH图的优劣,着重阐述了理论电位-pH图的绘制步骤及方法,列出了与电位-pH图绘制有关的4类反应。概述了人们在生成热力学稳定区-优势区(Predominanceareaphasediagram)的算法上的发展过程。联系当今科学研究及生产的需要,探讨了今后电位-pH图研究的重点和方向。
The significance and application of Eh-pH diagram were reviewed in detail. In this article, the differences between theoretical and experimental potential-pH diagrams were compared, the drawing methods of theoretical potential- pH were described, and four kinds of chemical reactions related to Eh- pH were listed also. The developing history of algorithms of predominance area phase diagram was described as well. The researching emphases and direction of Eh -pH diagram were discussed according to the urgent needs of scientific studies and industry.
