[Kinetic of complexation and sorption model]

Dear Jia Wang

Happy new year 

Once again with my problems.

I am using kinetic of complexation and sorption model  r_k=??∗?₊∗∏(?_?/?_? )^??∗(1−?/?) to predict dissolution and precipitation of wood ash. The model calculates the kinetics reaction (r_k) and the results are plotted as pH changes, species, minerals concentration. I would like to know how pH, species concentration are calculated using the kinetic reaction constant (rk). Can I have equations like:

1.  pH =  r_k…

2.  Ca⁺⁺ = r_k …

 

Sincerely

Hi Luis,

I misread your post above regarding 'rate constants' as 'thermodynamic constants'. Rate constants are usually derived from laboratory experiments and published in literature. My apologies for any confusion. 

Best regards,

Jia

Dear Jia wang! 

Thank you very much.

That´s why I asked some references for who knows and can recommend . 

 I appreciate your attention

Dear Jia Wang!

 

Thank you very much for your orientation. it very helpful. 

But now I have another problem!

What is the rate constant of Brianite and Sylvite?

Can I have some references about rates constant of Brianite and Sylvite? 

Sincerely

Dear Jian Wang !

Thank you very much for your orientation.

•  For how to consider the inhibitor and catalysts on modeling, your orientation is very helpful. thank you. 

But for the other issue, maybe I didn't clarify well. 

1. I intent to simulate a kinetic dissolution and precipitation of wood ash in water using react. The XRD of wood ash indicated the presence of Calcite, Brianite and Sylvite. Reactants pane doesn't have Brianite. So how to include this mineral (brianite) on simulation? How to add this mineral on reactants pane? 

Sorry for disturbing you. 

Sincerely 

Luis

Dear all!

 

I am Luis Savanguane, learning how to use GWB.

 

1. I want to know how GWB calculate pH, species concentration and mineral precipitation after get the kinetic reaction rate on kinetic of complexation and sorption model (react)? 

    Can I get the equations to quantify species contraction and pH change? 

2. How to introduce (consider)  inhibitors on modeling.

3. How to add mineral as reactant ?

 

Sincerely
