dong5600 Posted September 21, 2017 Share Posted September 21, 2017 Dear GWB： I have a question about making Eh-pH diagram to predict iron secondary minerals formed during iron reduction under anaerobic condition. My questions include： 1） When we choose the pair for Eh, is oxygen-e- the only choice? I could find other selections for Eh, but oxygen does not seem correct for anaerobic reaction, which typically exhibit negative Eh values. 2) For some of the solid phases, the ones showed up in the Eh-pH diagram were not observed in our study, while some of our observed ones did not appear. Is there any way I can check, modify or add some mineral information? Is solubility the only information needed for such analyses? Any suggestion is highly appreciated!
