Laura Lagos Posted February 14, 2014 Share Posted February 14, 2014 Hi everyone, I am working with minerals containing As and B (cahnite, teruggite and ulexite). My problem is that the database dont have them, and the data on internet (e.g.thereda) dont have them neither. Can I add these minerals to the database by an alternative way? I need to see saturation indexes and to model precipitation by evaporation too... Thanks all for reading my post, Laura. Quote Link to comment Share on other sites More sharing options...
Brian Farrell Posted February 14, 2014 Share Posted February 14, 2014 Hi Laura, You'll need an equilibrium constant K in order to calculate the saturation index of your minerals. You might find this in the literature (the value itself or a log K) for a reaction involving the mineral, or you might find information about the free energy of formation of the mineral, which you can use to calculate the equilibrium constant. Hope this helps, Brian Farrell Geochemist Aqueous Solutions LLC Quote Link to comment Share on other sites More sharing options...
