> I have a problem that I'll like to model with Phreeqc. The transport pathway should consist of ten cells having (two) different compositions. Futhermore in some of the cells a kinnetic reaction will occur. For example: > Cell 1-2: dissolution of UO3 > cell 3-4: dissoltion of UO3 and UO2 > Cell 5-10: reduction of organic carbon (CH2O - kinetic reation) > In this case an initial solution (rain water) going trough the ten cells will be modified during the transport (precipitation of UO2 ist expected, I modeled it in batch but I'll be satisfied to observed it in a dynamic system). > The example I've found on your site are dealing with cases where cells 1-10 als quite identical. You can define each cell to contain different sets of equilibrium_phases and kinetic reactions. The last definition in the series will be used in the column. The following is a rough outline of the input file you need. SOLUTION 0-10 Rainwater END USE solution 0 EQUILIBRIUM_PHASES 1-2 UO3 0 .1 SAVE solution 1-2 END USE solution 0 EQUILIBRIUM_PHASES 3-4 UO3 0 .1 UO2 0 .1 SAVE solution 3-4 END KINETICS 5-10 Organic_decay ...
