Hi, this is a good coincidence, but I think I do something very similar to
what you just described.

I use umbrella sampling to estimate the free energy profile as a function
of distance from a liquid-vapor interface. Then, the free energy cost of
adsorption to the interface can be approximated. I can imagine that it
should work just as well with liquid-solid interfaces.

I found these references helpful.
