Jeonghwan Hwang Posted September 25, 2019 Share Posted September 25, 2019 Hi, this is Jeonghwan Hwang, Thank you for reading. I want to make a reactive transport modeling of fluid in montmorillonite-Ca. At first time, i need to make the converged initial condition and use react with 'thermo.com.V8.R6+'. 1) I used the initial water composition with field data. HCO3- ion was selected to balacing ion because balancing with Cl- could not converge the model. 2) I put the reactants 'montmor-Ca' and put the rate 0.1 volume%/yr After run, I saw that the pH of fluid was rapidly decreased at first term of my model. At first, i think my model should increase the pH, because the reaction of montmorillonite-Ca need H+ ion. Can anyone please answer to my question? Thank you.
