2 Set the simulation’s duration
Set the initial fluid composition and mass of sorbing minerals on the Basis pane. Fe(OH)3(ppd) sorbs ions. The number of surface sites is proportional to its mass Set the simulation’s duration

3 Surface complexation dataset for hydrous ferric oxide.
File → Open → Sorbing Surfaces… Surface complexation dataset for hydrous ferric oxide.

4 Sorbed species… >(w)FeOCa+
Set up a pH buffer and kinetic rate law on the Reactants pane. add → Fixed → pH add → Kinetic → Sorbed species… >(w)FeOCa+

5 Supply kinetic parameters
pH buffered to initial value Supply kinetic parameters Initial concentration of surface complex Rate constant Desorption rate is proportional to the concentration of the >(w)FeOCa+

6 Desorption of Ca++ from a ferric oxyhydroxide surface
