Pitzer's parameters for Al3+

[Laknesh]

Hello,
I am modelling batch-reaction calculations for ionic strength more than 4.4 M. I have to use Pitzer database for better prediction. I could find the Pitzer's parameters for the species which I am considering in the calculation except Al3+. Can anyone provide the Pitzer's parameters for Al3+ to use in PHREEQC.

Thank you

The pitzer.dat database does not have parameters for aluminum. The initial parameterizations were for strong electrolytes, however, there has been much more work on many elements. Perhaps you can find literature relevant to aluminum.

Thank you for your quick response. I will the data in literature.

Thank you

Hi Laknesh,

I am also using PHREEQC to model high ionic strength waters (1-4 molal). The primary minerals of concern in my study are aluminosillicates such as kaolinite and K-feldspar. Obviously the inclusion of silica in the latest Pitzer database is a huge step forward, but aluminum is still not included. Did you have any luck in your literature search? I will let you know if I find any useful data, too. Thanks.

Hello!

Can you tell me where did you find Pitzer database with silicates. Are you sure that it exist?
