Hi I wonder if you could please help. I am trying to model a column expt using PHREEQC The column is a mixture of sand and clay ( mixtures of illite, kaolinite, chlorite or montmorillonite) with known ionic exchange parameters. I am adding to this a binary chloride salt mixture and want to model the breakthrough curves using exchange and transport keywords. I have tried using the solid_solutions keyword to set the initial conditions in the column but am unable to do so. My only other thought I guess is to set solution 1-x using the formula for the clays. Could you tell me if I am on the right track, sorry but I am new to this type of modelling and I am trying to learn as I work through so any help would be greatly received Thankyou for your time Karen KAREN.
