Hi Campbell,
So what is reacting? Only your cations, or also the solvent? Have you coupled both the flow and the ion concentrations at the interface between the free and the porous region? Are you actually removing the reactants from the solution when you are depositing (maybe a wrong sign in the reaction rate?)?
