Hello,
I am currently working on modeling the precipitation of seawater under evaporation. I am particularly concerned with the Iron containing phases.
Which thermodynamic database should I choose to get a reliable result? "HMW" could have been an excellent choice except that it does not contain Fe. The other databases that are present include Fe as well as use B-dot equations. Generally B-dot is valid for Ionic Strengths less than 3 molal , but there were erroneous results (pg 132) cited in the book "Geochemical and Biochemical Reaction Modeling" by Craig Bethke. I am very perplexed with the choice of database. Please suggest a solution.
Thank you
