Hi, thank you for reading.
I wanted to make a phase diagram of Ca-montmorillonite, but I know that I have to define the geochemical condition properly.
So, I am going to make a initial water composition of bentonite.
For this reason, I use 'react' and put the initial groundwater composition of Gyeongju deep groundwater at 'Basis' and Montmor-Ca at 'Reactants'.
I used thermo.com.V8R6+ to define Ca-montmorillonite.
The temperature was defined at '130 cel' which was usually used in high-level radiowaste disposal.
Unchecked 'precipitation' at iteration, because I want to make only groundwater condition.
Finally, I defined 300 yr to make a equilibrium condition.
The question is below;
1) why did H+ moles in final results show negative value (-164)? And, can i solve it?
2) the results showed the same pattern with different time scale, 10 yr, 300 yr, 1 yr. why did this results present?
3) are there any method to approach the results more precisely?
Thank you.
Sincerely,
Jeonghwan Hwang
