We need to evaluate the saturation index for building the equilibrium diagrams (precipitation/dissolution) major chemical forms in solution. Thank you very much in advance!
Dear Mr. Karbassi, thank you very much. Actually, we were looking for the calculation of SI for geological materials (dolomite, calcite). Finally we used PHREEQC program.
I recommend "visualMINTEQ and Aqion", there are very easy to use. But, these software designed for aqueous solutions.
However, the calculation of SI for a co-solvent solution such as Methanol and brine water will be very difficult.
It is well known that the activity coefficient of mineral ions are changed in a co-solvent system, specifically in alcohol solutions. Therefore, I think these kind of software are very limited.
So can anybody advice me which free access software handle co-solvent SI calculations?
