claudiaacosta Posted July 30, 2015 Share Posted July 30, 2015 Hi Katelyn, Thank you again for your help!!!. Now, I have a new question!!! I am trying to complete a database to simulate a pore water contaminated with U(VI). The cation and anion components present in this porewater are mainly Na, Si, K, HCO3, Al, NO3, Ca, Cl, and UO2++; at a pH between 7 and 8. I will also use the react model to slide the pH to different conditions. I revised the provided Geochemist's Workbench thermo databases, and I found that the thermo data includes most of my porewater components as well as most of the uranium solid phase that I want to see after my simulation. However, it doesn't include H2SiO4 (to swap with H2SiO4-- to simulate all the polysilicate species) and UO2++. In order to include the missing species; I copied them from the minted data following the next procedure: 1. I renamed the thermo.dat 2. From the minteq data on the basic section, I copied H2SiO4 and UO2++ on the same section of the renamed data. 3. From minteq data on the aqueous species section, I copied +H2SiO4-- and H3SiO4- on the same section of renamed data. I noted after copying these species that they were saved as a COPY (H2SiO4--_COPY, H3SiO4-_COPY, and UO2++_COPY) since they are included in the thermo data in the redox section. My questions is if I can remove these species from the redox section without creating any conflict in the data or I should just transfer these species from the redox thermo data to the basic section. Thank you very much!!! Claudia Quote Link to comment Share on other sites More sharing options...
