Hi everyone, I am very new to SpecE8, and I am trying to predict the speciation given a defined environment. You can see my parameters in the attached screenshot. My O2(g) is zero because I have an anoxic environment, but these input seem to not return any speciation, would anyone take a look what was wrong with my set up? Thanks!

Hi everyone! I would like to know if anyone had experience adding the mineral, mopungite {Na[Sb(OH)6]} into any of the database. I went through all the pre-set database GWB has and was not able to locate this mineral. If anyone wrote mopungite into a database it would be a great help if the details can be shared. Thank you all!

Hi All! I am trying to make a pH-Eh diagram for the species Sb(OH)6-, although the species SbO2 appeared in the diagram as well (attached is the diagram I made). I was wondering is there any way to suppress SbO2? Thank you!!

Hi Jia, Thank you so much for your kind explanation, I was able to complete the copy and now I can proceed to make pH-Eh diagram. Thank you!

Hi Jia, thank you so much for your reply. After switching the dataset I was able to look for Sb species. I also checked the old thread you provided and it helped a lot! However I am encountering the same issue that was in the old thread where "Reaction for H2(g) is missing; can not plot water limit" message pop up when I use thermo.minteq dataset to create Eh-pH graph. I tried to follow the solution in the original thread which is to add H2 to a copy of the minteq database. I tried couple of times but it was not working for me, would it be possible for you to describe how to add H2 to the database? Thank you so much!

Hey all, I am looking to create a pH-Eh diagram for the element Antimony (Sb), but it seems like I could not find this element in Act2, I wonder if I need subscription to 'unlock' this element? If anyone can help with this it will be much appreciated. Thanks!
