Hello Qianwei,
You can use TEdit, the graphical thermo data editor, to see which dataset may be appropriate for your work. To load a given dataset into the GWB program go to File -> Open -> Thermo Data… If there’s a species that’s not included in one dataset, you can easily copy a species from one dataset to another, or add data from the literature. For more information, see the TEdit section in the GWB Essentials Guide. You can also view tutorials on how to edit thermo datasets here.
Kind regards,
Katelyn
Hello Qianwei,
Can you please attach your Act2 (.ac2) and your SpecE8 file (.sp8)? That way I can take a better look at the issue you are having.
Thank you,

Hi Katelyn,
Many thanks for your reply. And I tried to use another thermo dataset in with Act2 and I found the La+++ I wanted, but I got another problem when I tried to draw the pH-Eh diagram. There is no minerals's state in the diagram and it always show the La++ without La+++ which is more stable. Could you help me with this? I used the SpecE8 for the activity calculation of La+++ ion but the results always come to be the activity of La++. Thanks again.

Hi there,
I am just a new user of GWB student version and I wonder how could I find the La+++ in the species list. Thank you very much!

Hi Katelyn,
Thank you for your help and now I got another problem. I applied the log activity of species in SpecE8 in the Act2 program, but the results does not match at all. According to the results of SpecE8, the only saturation mineral is La2(CO3)3-8H2O while in the pH-Eh diagram, there is no mineral precipitation. Could you help me figure out what the problem is? Attached is my results. Thank you very much!
