Potential-pH diagrams, which summarize the thermodynamic properties of a system, are extensively used for interpreting the corrosion behavior of metals in condensed media. In this paper, E-pH diagrams are presented for iron and nickel in sulfide-containing high-salinity geothermal brine at 25°C and 250°C. The diagrams have been constructed on the assumption of a constant total sulfide constraint which leads to nonlinearity of the equilibrium relationships in potential-pH space. The application of these diagrams in the interpretation of chemical and corrosion processes in geothermal systems is briefly discussed.
