Computer methods for calculating and plotting high temperature eh pH diagrams

Abstract

 Based on previous work, a computer program for calculating and drawing high-temperature Eh-pH diagrams was adapted. Applying this program can quickly and accurately calculate Eh-pH diagrams under different temperatures, different components, and different activity conditions, and obtain intuitive and clear graphics. The calculation method of this program is simple and highly versatile. After further improvement, it can be used to compile Eh-PH, Eh-pC_i, or pC_i-pH atlas under different temperature and activity conditions of mineral and aqueous solution systems.
