Oleh Weres Posted October 22, 2012 Share Posted October 22, 2012 When I was using GW7 Standard I added glycolate as a basis species and glycolic acid as a derived species to THERMO and it worked fine. I was careful to change the number of species in both places. Using the same modified data base with GW9 Standard gives weird results: Elemental Fe precipitates from geothermal brine. So now I am using the original THERMO modified only by substituting in correct values for solubility of amorphous silica and quartz, and GW9 works fine again. ?????

Brian Farrell Posted October 23, 2012 Share Posted October 23, 2012 Hi Oleh, If you post your two modified thermo datasets, your script, and some sort of plot or explanation of the old and new results I'd be happy to take a look.

Oleh Weres Posted January 10, 2013 Author Share Posted January 10, 2013 Problem solved; it was due to bad data for "Iron" as mineral in the database, NOT due to addition of Glycolate. Quote Link to comment Share on other sites More sharing options...
