Example 5–Irreversible Reactions
Description
This example demonstrates the irreversible reaction
capabilities of PHREEQC in modeling the oxidation of pyrite. Oxygen (O2) and
NaCl are added irreversibly to pure water in six amounts (0.0, 0.001, 0.005,
0.01, 0.03, and 0.05 mol); the relative proportion of O2 to NaCl in the
irreversible reaction is 1.0 to 0.5. Pyrite, calcite, and goethite are
allowed to dissolve to equilibrium and the carbon dioxide partial pressure
is maintained at 10-3.5 (atmospheric partial pressure). In addition, gypsum
is allowed to precipitate if it becomes supersaturated. The example can be
run using the phrRunString routine.
