> one of my students is using PHAST/PHREEQC for a term project and we would like to consider additional components. I am not quite sure how to do accomplish that at this point in time. For example, we would like to include a few chlorinated solvents as components (solution_master_species), which will particpiate in kinetic reactions. Could you let me know what is the best way to include new components? Here's an example that adds benzene plus kinetic decay. It should be enough to get you started.
