Dien Li Posted October 26, 2011 Share Posted October 26, 2011 Hi, Brian I am a scientist at SRNL. I have an aqueous solution system that may contain Fe, Ca, Cu, Mn, Zn, NH4, Cl, NO3, PO4, BO3. It is Ca, NO3 and NH4 dominant. I like to model the speciation of Fe (either soluble species or precipitates) vs (1) the solution pH; (2) the initial Fe concentration; (3) the initial P concentration. I like to know which module (e.g., SPEC8 or REACT...) I need to use to achieve this goal. If SPEC8 is supposedly to calculate the species in the equilibruim state systems, SPEC8 can not calculate the species change against the pH or initial concentrations, is it right? I also tried REACT, but it looked that no data was obtained after RUN. Please instruct me on how I can apporach this project, thanks.
