Fe precipitation, how to cuantify each mineral precipitation

[javiera.aedo]

Hello, I'm trying to remove Fe through the precipitation of Fe(OH)3(a), Goethite and Hematite and I want to know how much Fe remove each PHASES and I don't know how to GRAPH

It doesn't seem you have worked too hard to try to learn how to do what you want to do. Here is a script that should serve as a start. The transfers of the minerals are in the output file.

If you want to generate a graph, you need to add a USER_GRAPH data block. You could add the REACTION in multiple steps and plot the changes in minerals. You would need to use Basic functions described in the section on the Basic interpreter to get the values to be plotted.

SOLUTION 1
Fe(2) 1
Cl    2
END
USE solution 1
REACTION
O2 1
0.1 mmol
EQUILIBRIUM_PHASES 1
Fe(OH)3(a) 0 0
Goethite   0 0
Hematite   0 0
