Hi

dlparkhurst:
Wow. What is the theory of using whey? The only thing I can think is that the organic compounds in whey act as ligands to help dissolve ore minerals. If that is the case, llnl.dat and minteq.v4.dat have some data for organic ligands. Still I'm not sure if these databases would be the answer. You might need a more complete model for organic binding, like WHAM or NICA, which is not available in PHREEQC.

dlparkhurst:
Sorry, the minteq.v4.dat has a number of ligands, but not lactate or glucose.

dlparkhurst:
Yes. Then you need to find thermodynamic constants for Glucose-ligand aqueous reactions if the glucose is to have any effect on mineral solubility. So, you need a constant for something like the following:


--- Code: ---SOLUTION_SPECIES
Glucose + Zn+2 = GlucoseZn+2
log_k ??

--- End code ---
