Equilibrium Solubility Based on Aqueous Speciation

Ryan Roper -

This model shows an approach for calculating the solubility an an element based on equilibrium chemistry that includes solid phase dissolution-precipitation and aqueous speciation similar in concept to a thermodynamically based geochemical model. The mineral gibbsite, Al(OH)3, is used for the solid phase and dissolved Al-hydroxyl and Al-sulfate species are used to represent the aqueous speciation. These results are presented as a solubility curve of dissolved aluminum as a function of pH.
