Capillary geochemistry - water pressure and thermodynamics

It has been known for some time that capillary pressure can impact thermodynamic properties of water, solutes and minerals, especially under high suction conditions. I have been wondering about the possibility to account for the impact of capillary pressure on thermodynamic constants used in equilibrium calculations.

Best regards,

Hi,

there might be a feature in HP1 which I included which is able of doing that. But I am not 100% sure, and of course, it is not tested.

The thing about using capillary pressures is that it is not a very good assessment of the real situation because it lumps all the surface interactions together
just found this myself
